| CVE-2026-72011 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390/diag: Add missing array_index_nospec() call to memtop_get_page_count() 'level' is user space controlled and used to read from an array. Add the missing array_index_nospec() call to prevent speculative execution. | ||||

| In the Linux kernel, the following vulnerability has been resolved: liveupdate: validate session type before performing operation The sessions ioctls are not applicable to all session types. PRESERVE_FD is only applicable to outgoing sessions. RETRIEVE_FD and FINISH are only valid for incoming session. Calling a incoming ioctl on an outgoing session is invalid and can cause file handlers to run into unexpected errors. For example, a user can create a (outgoing) session, preserve a memfd, and then immediately do a retrieve without doing a kexec in between. This would result in memfd's retrieve handler to run. The handlers expects to be called from a post-kexec context, and will try to do a kho_restore_vmalloc() or kho_restore_folio() to try and restore memory. KHO catches this (thanks to KHO_PAGE_MAGIC) and returns an error, but since this is considered an internal error and KHO throws out a bunch of WARN()s. Associate a type with each ioctl op and validate the type in luo_session_ioctl() before dispatching the ioctl handler to make sure the op is being called for the right session type. | ||||
| CVE-2026-72021 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 8.2 High |
| In the Linux kernel, the following vulnerability has been resolved: ipvs: use parsed transport offset in SCTP state lookup set_sctp_state() reads the SCTP chunk header again in order to drive the IPVS SCTP state table. For IPv6 it computes the offset with sizeof(struct ipv6hdr), while the surrounding IPVS code uses iph.len from ip_vs_fill_iph_skb(), where ipv6_find_hdr() has already skipped extension headers and found the real transport header. This makes the state machine read from the wrong offset for IPv6 SCTP packets that carry extension headers. For example, an INIT packet with an 8-byte destination options header can be scheduled correctly by sctp_conn_schedule(), but set_sctp_state() reads the first byte of the SCTP verification tag as a DATA chunk type. The connection then moves from NONE to ESTABLISHED instead of INIT1, gets the longer established timeout, and updates the active/inactive destination counters incorrectly. This happens even though the SCTP handshake has not completed. Use the parsed transport offset passed down from ip_vs_set_state() for the SCTP chunk-header lookup. For IPv4 and IPv6 packets without extension headers this preserves the existing offset. | ||||
| CVE-2026-72046 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: gve: fix header buffer corruption with header-split and HW-GRO The DQO RX datapath programs a per-buffer-queue-descriptor header_buf_addr at post time and reads the split header back at completion time. Both the post and the read currently index the header buffer by queue position rather than by the buffer's identity: - post (gve_rx_post_buffers_dqo): header_buf_addr is computed from bufq->tail - read (gve_rx_dqo): the header is read from desc_idx (the completion queue head index) This relies on the buffer-queue index and the completion-queue index being equal for the start of every packet, i.e. on the device consuming posted buffers and returning completions in the exact same order. That assumption does not hold once HW-GRO is enabled with multiple flows: coalesced segments are accepted and completed in an order that may differ from the order buffers were posted, and segments from different flows may interleave. That results in two problems: 1. Wrong header slot on read. Because the read offset is derived from the completion index (desc_idx) while the device wrote the header to the address programmed for the buffer's buf_id, the driver can copy a header belonging to a different packet. This shows up as throughput drop (about 30% drop and large numbers of TCP retransmissions) with header-split and HW-GRO both enabled and many streams. 2. Header buffer reused while still owned by the device. The driver advances bufq->head by one per completion and re-posts buffers based on that. Arrival of N RX completions only guarantees that at least N RX buffer descriptors have been read by the device. It does not guarantee that the device has relinquished the ownership of all the buffers corresponding to those N descriptors. With out-of-order completions (e.g. the completion for a packet copied into buffer N arrives before the completion for a packet copied into buffer N-1), the driver can re-post and overwrite a header buffer that the device is still going to write into, corrupting the header of a packet whose completion has not yet been processed. Fix both issues by indexing the header buffer by buf_id on both the post and read paths. Reading from buf_id's slot is therefore always correct regardless of completion ordering (fixes problem 1). Indexing by buf_id also ties each header slot to the lifetime of its buffer state. A buffer state is only returned to the free/recycle lists when its own completion (buf_id) is processed, so its header slot can only be re-posted after the device is done with it. This makes header slot reuse safe under out-of-order completions (fixes problem 2). Allocate (gve_rx_alloc_hdr_bufs) and free (gve_rx_free_hdr_bufs) the header buffers based on num_buf_states to match the buf_id indexing. | ||||
| CVE-2026-72060 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: icssg: guard PA stat lookups icssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name() with FW PA stat names regardless of whether the PA stats block is present on the hardware. emac_get_stat_by_name() already guards the PA stats lookup with `if (emac->prueth->pa_stats)`; when that pointer is NULL the lookup falls through to netdev_err() and returns -EINVAL. Because ndo_get_stats64 is polled regularly by the networking stack this produces thousands of log entries of the form: icssg-prueth icssg1-eth end0: Invalid stats FW_RX_ERROR A secondary consequence is that the int(-EINVAL) return value is implicitly widened to a near-ULLONG_MAX unsigned value when accumulated into the __u64 fields of rtnl_link_stats64, silently corrupting the rx_errors, rx_dropped and tx_dropped counters reported by `ip -s link`. Every other PA-aware code path in the driver is already guarded with the same `if (emac->prueth->pa_stats)` check. Apply the same guard here. | ||||
| CVE-2026-72106 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm-ioctl: fix a possible overflow in list_version_get_info sizeof(tt->version) is 12 bytes, but the code writes 16 bytes into the output buffer - info->vers->version[0], info->vers->version[1], info->vers->version[2] and info->vers->next. This can cause buffer overflow. Fix this buffer overflow by replacing "sizeof(tt->version)" with "sizeof(struct dm_target_versions)". | ||||
| CVE-2026-72065 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: net: mana: Validate the packet length reported by the NIC Validate the packet length reported in the RX CQE before passing it to skb processing. The CQE is supplied by the NIC device and should not be blindly trusted. | ||||
| CVE-2026-72076 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix out-of-bounds read in ims_pcu_irq() debug logging The debug logging in ims_pcu_irq() unconditionally prints data from pcu->urb_in_buf. However, if the interrupt fired for pcu->urb_ctrl, the actual data resides in pcu->urb_ctrl_buf. If urb->actual_length for the control URB exceeds pcu->max_in_size, this leads to an out-of-bounds read. Fix this by printing from the correct buffer associated with the URB. | ||||
| CVE-2026-72078 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - validate control endpoint type The driver currently assumes that the first endpoint of the control interface is an interrupt IN endpoint without verifying it. A malicious device could provide a different endpoint type, which would then be passed to usb_fill_int_urb(), potentially leading to kernel warnings or undefined behavior. Verify that the control endpoint is an interrupt IN endpoint. | ||||
| CVE-2026-72361 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe/hw_engine: Fix double-free of managed BO in error path The error path in hw_engine_init() explicitly frees a BO allocated with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm(). Since the managed BO already has a devm cleanup action registered, this causes a double-free when devm unwinds during probe failure. Remove the explicit free and let devm handle it, consistent with all other xe_managed_bo_create_pin_map() callers. (cherry picked from commit e459a3bdeb117be496d7f229e2ea1f6c9fe4080b) | ||||
| CVE-2026-72089 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Reject firmware log with size smaller than header fw_log_from_bo() validates the tracing buffer header_size and that the log fits within the BO, but never checks that log->size is at least log->header_size. fw_log_print_buffer() then computes: u32 data_size = log->size - log->header_size; which underflows to a near-U32_MAX value when firmware reports a log whose size is smaller than its header. That huge data_size defeats the log_start/log_end bounds clamps added by commit dd1311bcf0e6 ("accel/ivpu: Add bounds checks for firmware log indices"), so fw_log_print_lines() reads far past the small real data region of the BO. A size of 0 also makes fw_log_from_bo() advance the offset by 0, causing the callers to loop forever on the same header. Reject logs whose size is smaller than the header (which also rejects size == 0). | ||||
| CVE-2026-72155 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: swp: Improve locking user experience In the case of the first block being locked (or the few first blocks), if the user want to fully unlock the device it has two possibilities: - either it asks to unlock the entire device, and this works; - or it asks to unlock just the block(s) that are currently locked, which fails. It fails because the conditions "can_be_top" and "can_be_bottom" are true. Indeed, in this case, we unlock everything, so the TB bit does not matter. However in the current implementation, use_top would be true (as this is the favourite option) and lock_len, which in practice should be reduced down to 0, is set to "nor->params->size - (ofs + len)" which is a positive number. This is wrong. An easy way is to simply add an extra condition. In the unlock() path, if we can achieve the same result from both sides, it means we unlock everything and lock_len must simply be 0. A comment is added to clarify that logic. | ||||
| CVE-2026-72220 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: sunrpc: harden rq_procinfo lifecycle to prevent double-free The svc_release_rqst() function executes the callback inside rqstp->rq_procinfo->pc_release. However, if a worker thread begins processing a new request and encounters an early error path (e.g., unsupported protocol, short frame, or bad auth) before a valid rq_procinfo is installed, a stale release hook can be re-triggered against reused state from the previous RPC, resulting in a double-free or use-after-free vulnerability. Harden the lifecycle of rq_procinfo by: 1. Ensuring svc_release_rqst() always clears rq_procinfo after the optional pc_release() call, regardless of whether the hook exists. 2. Explicitly clearing rq_procinfo at request entry in svc_process() before any early decode or drop paths. 3. Ensuring svc_process_bc() does the same at backchannel entry. This guarantees that error flows will not encounter a non-NULL stale rq_procinfo pointer when there is nothing to release. | ||||
| CVE-2026-16708 | 1 Ibm | 1 Db2 Mirror For I | 2026-08-18 | 8.3 High |
| IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote attacker to obtain sensitive information due to external control of system configuration. | ||||
| CVE-2026-72102 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: dm_early_create: fix freeing used table on dm_resume failure If dm_resume fails, the kernel attempts to free table with dm_table_destroy, but the table was already instantiated with dm_swap_table. This commit skips the call to dm_table_destroy in this case. | ||||
| CVE-2026-72105 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: dm-log: fix a bitset_size overflow on 32bit machines Commit c20e36b7631d ("dm log: fix out-of-bounds write due to region_count overflow") made sure that region_count could fit in an unsigned int. But the bitmap memory isn't allocated based on region_count. It uses bitset_size (a size_t variable). The first step of calculating bitset_size is to set it to region_count, rounded up to a multiple of BITS_PER_LONG. If region_size is less than BITS_PER_LONG smaller than UINT_MAX, it will get rounded up to 2^32. On a 32bit architecture, this will make bitset_size wrap around to 0 and fail, despite region_count being valid. Since bitset_size gets divided by 8, it can hold any valid region_count. It just needs a special case to handle the rollover. If it is 0, the value rolled over, and bitset size should be set to the number of bytes needed to hold 2^32 bits. | ||||
| CVE-2026-74578 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: algif_skcipher - force synchronous processing on trees without ctx->state The AIO/async path in skcipher_recvmsg() passes the socket-wide ctx->iv directly into the skcipher request. After io_submit() the socket lock is dropped and the request is processed asynchronously, so a concurrent sendmsg(ALG_SET_IV) can overwrite ctx->iv and make the in-flight request run under an attacker-controlled IV. For CTR/stream modes this is IV/keystream reuse and lets an unprivileged user recover the plaintext of a concurrent operation. Snapshotting ctx->iv into per-request storage for the async path is not sufficient. For ciphers with statesize == 0 - which includes cbc and ctr - the MSG_MORE inter-chunk IV chaining is carried solely by the in-place req->iv writeback, which a snapshot redirects into per-request memory that af_alg_free_resources() releases on completion, silently producing wrong output. Writing the IV back from the completion callback instead is not possible either: that would require lock_sock() there, but the callback can run in softirq/atomic context, so it must not sleep. Make the operation synchronous instead, which removes both the IV race and any writeback race. This is equivalent to the upstream resolution, commit fcc77d33a34c ("net: Remove support for AIO on sockets"), which removed the AIO socket path across net/ entirely and so produces the same end state for this file. This patch deviates from that commit deliberately: rather than removing AIO socket support tree-wide, which would be far too invasive for stable, it removes only the AIO branch in crypto/algif_skcipher.c. io_submit() now completes synchronously; AF_ALG async is rarely used in practice. The -EIOCBQUEUED check in skcipher_recvmsg() is now dead but harmless, and is left alone to keep the fix minimal. Tested on 6.6.y: attacker IV injection dropped from 2296/200000 to 0/200000 after the change; MSG_MORE chunked CTR output bit-identical to single-shot. | ||||
| CVE-2026-73650 | 1 Svg | 1 Svgo | 2026-08-18 | 8.2 High |
| SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 1.0.0 until versions 2.8.3, 3.3.4, and 4.0.2, the removeScripts plugin, named removeScriptElement in versions 1 through 3, can leave executable content in optimized SVGs because it does not remove namespaced or prefixed script elements such as <svg:script> and, in versions 3 and 4, matches JavaScript URIs case sensitively. Applications that process untrusted SVG input with this plugin enabled and serve the result can allow scripts to execute when another user opens the SVG, exposing local storage or cookies. This issue is fixed in versions 2.8.3, 3.3.4, and 4.0.2. | ||||
| CVE-2026-72836 | 1 Filebrowser | 1 Filebrowser | 2026-08-18 | 8.1 High |
| FileBrowser before 2.63.19 does not account for case-insensitive filesystems when checking home directory ownership during self-registration. When Signup and CreateUserDir are enabled and FileBrowser's root is on a case-insensitive filesystem (confirmed on Windows/NTFS), two self-registered usernames that differ only in letter case (e.g., CaseVictim and casevictim) are stored as distinct accounts but resolve to the same physical home directory, because the scope-ownership check compares the persisted scope as an exact case-sensitive string. A second registrant can therefore read, overwrite, and delete another account's files through authenticated HTTP endpoints, without needing an existing account or victim interaction. | ||||
| CVE-2026-45699 | 1 Netatalk | 1 Netatalk | 2026-08-18 | 7.5 High |
| Netatalk is a Free and Open Source file server suite for Unix-like operating systems. In versions 3.1.19 through 4.4.2, a stack-based buffer overflow exists in the copydir() function of Netatalk's afpd daemon due to an integer underflow in the calculation of the remaining buffer size used for path construction. copydir() is a utility function called when a file operation crosses a device boundary inside an AFP shared volume, which the standard library's renameat() cannot handle. The function attempts to track available buffer space using srem and drem for source and destination paths. Incorrect arithmetic causes both srem and drem to underflow to SIZE_MAX. Consequently, boundary checks against strlen(de->d_name) always pass, allowing strcpy() to append filenames into nearly full stack buffers. Version 4.4.3 patches the issue. As a workaround, configure each AFP shared volume to be structured as a single file system, in other words no subdirectory of a shared volume should be a mount point for a different file system. | ||||
