| In the Linux kernel, the following vulnerability has been resolved:
media: cec: Serialize exclusive follower delivery
cec_receive_notify() reads the exclusive follower pointer without the
adapter lock. Serialize the no-follower check and message delivery
against mode changes and release. |
| If a BIND resolver has cached a tree of SVCB/HTTPS AliasMode records, and is then queried for the root of that tree, the resolver will spend disproportionate CPU time constructing the response.
This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: clamp the isolation index for rings outside a partition
adev->isolation[] has one slot per partition, but a ring that is not
assigned to one keeps AMDGPU_XCP_NO_PARTITION, which is ~0, so indexing
the array with it is out of bounds. SDMA submissions hit this on both
the isolation enforcement and the VM flush path and trip UBSAN.
Fall back to the first slot the way the cleaner shader path already
does, and stop taking the address before the ring type check that makes
it relevant. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: validate plane degamma LUT size for private color prop
Unlike the CRTC degamma path, which is guarded by
amdgpu_dm_verify_lut_sizes(), the per-plane degamma LUT size was never
validated before use. __set_dm_plane_degamma() passed the user-supplied
size straight into __is_lut_linear() and, for a non-linear LUT, into
__set_input_tf() -> __drm_lut_to_dc_gamma(), the latter always iterating
MAX_COLOR_LUT_ENTRIES entries regardless of the actual LUT size.
A malformed AMD_PLANE_DEGAMMA_LUT blob (e.g. a single entry) could thus
trigger a divide-by-zero in __is_lut_linear() or an out-of-bounds read in
__drm_lut_to_dc_gamma(). Reject any plane degamma LUT whose size does not
match MAX_COLOR_LUT_ENTRIES, mirroring the invariant the code already
asserts a few lines below (and which the CRTC path enforces).
The AMD_PLANE_DEGAMMA_LUT property is only exposed on builds with
AMD_PRIVATE_COLOR defined. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: fix firmware control interface bounds checks
panthor_init_cs_iface() and panthor_init_csg_iface() validate firmware
control interface offsets with 32-bit arithmetic and the size of the host
wrapper structures. The offsets are derived from firmware-provided strides,
so the arithmetic can wrap before the bounds check, and the host wrapper
size is not the size of the firmware control interface being mapped.
Use 64-bit arithmetic for the computed offsets and validate against the
actual firmware control interface structure sizes with subtraction-based
bounds checks. Also validate that the shared section is large enough for
the global control interface before using it. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: harden firmware build-info bounds checks
panthor_fw_read_build_info() checks whether the metadata range fits in the
firmware image with hdr.meta_start + hdr.meta_size. Both fields are u32, so
the addition can wrap and let an out-of-bounds range pass validation.
The function also reads the "git_sha: " prefix without first checking that
the metadata is long enough, and meta_size == 0 can underflow the NULL
terminator index.
Use subtraction-based bounds checking and reject metadata that is too short
to contain the expected prefix and trailing NULL byte. |
| Dell ObjectScale, versions prior to ObjectScale 4.4.0.0, contains an Improper Authentication vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access. |
| djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, `djust.tenants` isolation was enforced only on the HTTP path. The current tenant was stored in `threading.local()` and set exclusively by the HTTP-only `TenantMiddleware`, so on the live (WebSocket/SSE) path `get_current_tenant()` was always `None` during mount and every event handler — and the tenant-aware `QuerySet` manager failed OPEN (returned the unfiltered queryset, ignoring `STRICT_MODE`), disclosing every tenant's rows to whoever held the socket. `threading.local` was additionally shared across connections on the `sync_to_async` executor thread. This issue is fixed in djust 1.0.7. Tenant storage moved to a `contextvars.ContextVar` (per async task); the resolved tenant is bound around WS/SSE mount and every dispatch; both managers scope the base queryset once and fail CLOSED (`.none()` under the default `STRICT_MODE`); and system check S006 warns when `STRICT_MODE=False`. No known workarounds are available on the live path. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to clear dirty flag on folio in error path
If node block is corrupted due to chksum mismatch or inconsistent
footer info, it needs to drop clear flag of node folio, in order
to persist inconsistent node data to storage. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: limit recovery filename logging to stored length
F2FS stores recovery filenames as a length plus a fixed-size i_name
buffer. The buffer is not NUL-terminated, but recover_inode() and
recover_dentry() print it with %s.
For a 255-byte filename, recovery logging can read past i_name into the
following raw inode fields.
Print the name with a precision bounded by i_namelen and F2FS_NAME_LEN. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: validate MOVE_RANGE destination size
F2FS_IOC_MOVE_RANGE checks the source range, but not the destination end
before updating i_size. A source hole can expose this: __clone_blkaddrs()
skips NULL_ADDR entries and returns success, so the caller can still extend
the destination inode with unchecked pos_out + len.
Reject destination overflow and use inode_newsize_ok() before extending
the destination inode. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: only redirty pinned folios in redirty_blocks
redirty_blocks() pins folios with read_cache_folio() and then walks the
same range again with filemap_lock_folio() to redirty them and drop the
references it took.
Commit 5951fee46bef ("f2fs: Use a folio in redirty_blocks()") changed
the second pass to a do/while loop. If read_cache_folio() fails before
anything is pinned, page_idx does not advance but the cleanup loop still
runs once.
If readahead has already populated the failed folio in page cache, that
extra iteration finds it and folio_put_refs(folio, 2) drops one
reference too many. Later drop_caches or reclaim can then report
"BUG: Bad page state".
Only redirty the range that was pinned successfully. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cec: extron-da-hd-4k-plus: add sanity check
Add check to prevent overflowing msg.msg[] in case the incoming data
is malformed. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: loongson: Fix error handling in ACPI property parsing
In loongson_card_parse_acpi(), the return value of
device_property_read_string() for the `codec-dai-name` property was
ignored. If the property is missing or invalid, an uninitialized pointer
would be used later, potentially leading to undefined behavior.
Fix this by checking the return value and propagating the error
appropriately. |
| In the Linux kernel, the following vulnerability has been resolved:
media: platform: mtk-mdp3: Fix SCP device refcounting
mdp_probe() first tries to get the SCP handle with scp_get(). When that
fails, it falls back to looking up the SCP platform device with
__get_pdev_by_id() and then reads its driver data.
The fallback lookup returns the platform device with a reference, just
like scp_get() does. However, the fallback path currently drops that
reference immediately after platform_get_drvdata(). The driver later
still calls scp_put(mdp->scp) unconditionally from the probe error path
and from mdp_video_device_release(), which drops the SCP device
reference again.
Keep the fallback reference until the existing scp_put() call, so that
the fallback path follows the same ownership rules as the scp_get()
path. |
| In the Linux kernel, the following vulnerability has been resolved:
media: i2c: ov02a10: fix endpoint parsing use-after-free
The ov02a10_check_hwcfg() function calls fwnode_handle_put(ep)
immediately after allocating and parsing the endpoint. However, it
subsequently calls fwnode_property_read_u32() using the same 'ep'
handle, leading to a potential use-after-free.
Additionally, reading the optional 'ovti,mipi-clock-voltage' property
used to overwrite the 'ret' variable. If the property was missing,
'ret' would become negative, and this failure code would be incorrectly
returned at the end of the function, causing probe to fail entirely.
Fix the use-after-free by moving fwnode_property_read_u32() before
the endpoint is parsed and freed. Avoid the error leak by not
assigning the result of fwnode_property_read_u32() to 'ret'. |
| In the Linux kernel, the following vulnerability has been resolved:
media: go7007: defer the ALSA v4l2 put until card release
go7007_snd_init() already takes a v4l2_device reference for the ALSA
side, but go7007_snd_remove() drops it immediately after calling
snd_card_free_when_closed().
That is too early when a userspace process still has the capture PCM open.
The ALSA card and its PCM callbacks remain alive until the last file is
closed, so the release path can still reach struct go7007 through
pcm->private_data and call go7007_snd_hw_free() after the V4L2 release path
has freed the object.
Move the matching v4l2_device_put() to the ALSA card private_free callback
so the existing ALSA reference covers the whole deferred card lifetime. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Correctly cap TLBI Range to the architural limit
TLB Invalidation by Range has a fairly powerful way of encoding pretty
large ranges in a small number of bits. This range can be based on an
arbitrary VA, which means it is pretty easy for a guest to generate an
overflow should the hypervisor be naive enough to add the range to the
base...
Make sure the range is capped to the limit dictated by the address bit
that determines the VA range. For an IPA invalidation, this is further
corrected down the line to ignore the upper range. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: nVM: Ensure INVVPID is emulated on the correct physical CPU
When emulating INVVPID, KVM executes INVVPID on the physical CPU using
vpid02 (instead of the L1 assigned VPID), after doing some validations
on the operands. However, it is possible that the physical CPU KVM
executes INVVPID on is different from the CPU L2 is running on.
For example, in the following scenario:
- L2 runs on CPU #1 and exits to L1 (vmx->nested.vmcs02.cpu=1)
- L1 migrates to CPU #2 and executes INVVPID
- KVM executes INVVPID on CPU #2
- L1 migrates back to CPU #1 and runs L2 (vmx->nested.vmcs02.cpu=1)
The TLB entries on CPU #1 are never invalidated, because INVVPID was
executed on CPU #2, and vmcs02 never ran on a different pCPU (i.e.
vmx_vcpu_load_vmcs() will *not* request KVM_REQ_TLB_FLUSH).
Ensure that INVVPID is being executed on the same pCPU that L2 last ran
on, and if not, fallback to clearing last_vpid=0 to trigger a full VPID
flush on the next nested VM-Enter (as KVM will detect L1 using a
different VPID for L2). If L2 ends up running on a different pCPU, KVM
will flush the TLB anyway through vmx_vcpu_load_vmcs(). |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix cs84xx use-after-free on host teardown
qla84xx_put_chip() drops the last reference to ha->cs84xx and frees it via
__qla84xx_chip_release() without clearing ha->cs84xx. During teardown it ran
before scsi_remove_host(), which is what removes the 84xx_fw_version host
sysfs attribute. A concurrent read of that attribute in the window between
the two calls executes qla24xx_84xx_fw_version_show(), which dereferences
the freed ha->cs84xx, resulting in a use-after-free.
Move qla84xx_put_chip() to after scsi_remove_host() in both
qla2x00_remove_one() and qla2x00_disable_board_on_pci_error(). Once
scsi_remove_host() returns, the sysfs attribute is gone and kernfs has
drained any in-flight show(), so no reader can touch cs84xx; the put still
runs before the host and ha are freed. |
