| CVE-2026-93165 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: platform/chrome: sensorhub: Fix memory overread in ring handler `max_response` and `sensor_num` are read from different EC commands: - `max_response` is from cros_ec_get_proto_info(). ec_dev->max_response = info->max_response_packet_size - sizeof(struct ec_host_response); - `sensor_num` is from cros_ec_get_sensor_count(). sensor_num = cros_ec_get_sensor_count(ec); With a malfunctioning EC firmware, it is possible that the `msg->insize` (i.e., `fifo_info_length` in the context) could be clamped in cros_ec_cmd_xfer() because `msg->insize` is greater than `max_response`. int fifo_info_length = sizeof(struct ec_response_motion_sense_fifo_info) + sizeof(u16) * sensorhub->sensor_num; This means the number of read bytes could be less than expected. As a result, the subsequent memcpy() in cros_ec_sensorhub_ring_handler() overreads the `resp->fifo_info` buffer. Check the return value of cros_ec_cmd_xfer_status() and abort if the number of bytes read does not match the expected length. | ||||
| CVE-2026-93164 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: uprobes/x86: Move optimized uprobe from nop5 to nop10 Andrii reported an issue with optimized uprobes [1] that can clobber redzone area with call instruction storing return address on stack where user code may keep temporary data without adjusting rsp. Fixing this by moving the optimized uprobes on top of 10-bytes nop instruction, so we can squeeze another instruction to escape the redzone area before doing the call, like: lea -0x80(%rsp), %rsp call tramp Note the lea instruction is used to adjust the rsp register without changing the flags. We use nop10 and following transformation to optimized instructions above and back as suggested by Peterz [2]. Optimize path (int3_update_optimize): 1) Initial state after set_swbp() installed the uprobe: cc 2e 0f 1f 84 00 00 00 00 00 From offset 0 this is INT3 followed by the tail of the original 10-byte NOP. After a previous unoptimization bytes 5..9 may still contain the old call instruction, which remains valid for threads already there. 2) Rewrite the LEA tail and call displacement: cc [8d 64 24 80 e8 d0 d1 d2 d3] From offset 0 this traps on the uprobe INT3. Bytes 1..9 are not executable entry points while byte 0 is trapped. 3) Publish the first LEA byte: [48] 8d 64 24 80 e8 d0 d1 d2 d3 From offset 0 this is: lea -0x80(%rsp), %rsp call <uprobe-trampoline> Unoptimize path (int3_update_unoptimize): 1) Initial optimized state: 48 8d 64 24 80 e8 d0 d1 d2 d3 Same as 3) above. 2) Trap new entries before restoring the NOP bytes: [cc] 8d 64 24 80 e8 d0 d1 d2 d3 From offset 0 this traps. A thread that had already executed the LEA can still reach the intact CALL at offset 5. 3) Restore bytes 1..4 of the original NOP while keeping byte 0 trapped and byte 5 as CALL. cc [2e 0f 1f 84] e8 d0 d1 d2 d3 From offset 0 this still traps. Offset 5 is still the CALL for any thread that was already past the first LEA byte. 4) Publish the first byte of the original NOP: [66] 2e 0f 1f 84 e8 d0 d1 d2 d3 From offset 0 this is the restored 10-byte NOP; the CALL opcode and displacement are now only NOP operands. Offset 5 still decodes as CALL for a thread that was already there. Tthere is only a single target uprobe-trampoline for the given nop10 instruction address, so the CALL instruction will not be changed across unoptimization/optimization cycles. Therefore, any task that is preempted at the CALL instruction is guaranteed to observe that CALL and not anything else. Note as explained in [2] we need to use following nop10: PF1 PF2 ESC NOPL MOD SIB DISP32 NOP10: 0x66, 0x2e, 0x0f, 0x1f, 0x84, 0x00, 0x00, 0x00, 0x00, 0x00 -- cs nopw 0x00000000(%rax,%rax,1) which means we need to allow 0x2e prefix which maps to INAT_PFX_CS attribute in is_prefix_bad function. Also changing the uprobe syscall error when called out of uprobe trampoline to -EPROTO, so we are able to detect the fixed kernel. The optimized uprobe performance stays the same: uprobe-nop : 3.129 ± 0.013M/s uprobe-push : 3.045 ± 0.006M/s uprobe-ret : 1.095 ± 0.004M/s --> uprobe-nop10 : 7.170 ± 0.020M/s uretprobe-nop : 2.143 ± 0.021M/s uretprobe-push : 2.090 ± 0.000M/s uretprobe-ret : 0.942 ± 0.000M/s --> uretprobe-nop10: 3.381 ± 0.003M/s usdt-nop : 3.245 ± 0.004M/s --> usdt-nop10 : 7.256 ± 0.023M/s [1] https://lore.kernel.org/bpf/20260509003146.976844-1-andrii@kernel.org/ [2] https://lore.kernel.org/bpf/20260518104306.GU3102624@noisy.programming.kicks-ass.net/#t | ||||
| CVE-2026-93163 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: hwrng: core - fix rng list on registration error hwrng_register(rng) does the following: 1. Checks if rng has name and read methods set 2. Checks if the name already exists 3. Adds rng to global rng_list 4. May try to set rng to current_rng If step 4 fails, it returns an error. However, it does not remove the rng from rng_list, causing a dangling reference which can result in use-after-free if the caller frees rng, since registration failed. Add a list_del_init() cleanup step. | ||||
| CVE-2026-93162 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: qat - cancel work on re-enable SR-IOV timeout The QAT reset worker queues SR-IOV reenable work using a work_struct and completion embedded in an on-stack adf_sriov_dev_data. If the completion wait times out, the reset worker can return while device_sriov_wq still holds or executes the stack-backed work item. Cancel the work on the device_sriov_wq on timeout before the stack frame unwinds. | ||||
| CVE-2026-93161 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: qat - clear AES key schedule from stack qat_alg_xts_reverse_key() expands the forward XTS AES key on the stack. That schedule contains key material and can remain in the stack frame. Clear the temporary crypto_aes_ctx with memzero_explicit() after the copy. | ||||
| CVE-2026-93160 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-ecc - reject hardware ECDH without a public key The hardware ECDH path in atmel_ecdh_compute_shared_secret() uses the private key stored in the device. However, the public key is cached only after atmel_ecdh_set_secret() successfully generated that private key for the current tfm. atmel_ecdh_generate_public_key() already rejects requests when no public key is cached. Add the same check to atmel_ecdh_compute_shared_secret() to prevent the device from using a private key that was not generated for the current tfm. | ||||
| CVE-2026-93159 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-sha204a - fix heap info leak on I2C transfer failure The nonblocking RNG path allocates a work_data structure to track the state of an in-flight asynchronous I2C request. This pointer is stored in rng->priv and later consumed by the read path once the transaction completes. If the underlying I2C transfer fails, the completion callback is invoked with a non-zero status. In this case, the allocated work_data is not usable for producing RNG output and must not remain associated with the hwrng state. Previously, the failure path only logged a warning but left the pointer state uncleared, which can result in subsequent read attempts observing stale state and interpreting it as valid completion data. Fix this by freeing the pending work_data. The I2C transaction reports an error. This ensures that failed requests do not leave residual state behind that could be interpreted as valid RNG data on later reads. Clearing rng->priv is done at the subsequent call to nonblocking read. | ||||
| CVE-2026-93158 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: sa2ul - stop probe if context pool creation fails sa_ul_probe() calls sa_init_mem() to create the DMA pool used for security context buffers, but ignores its return value. If pool creation fails, probe still continues with DMA setup, algorithm registration and child population even though later request setup depends on that pool. Stop probing when sa_init_mem() fails, and route that failure to the PM cleanup path without attempting to destroy an uncreated DMA pool. | ||||
| CVE-2026-93157 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: hwrng: xilinx-trng - propagate timeout before any data is read xtrng_readblock32() polls for 16-byte chunks but returns the number of bytes read even when the first poll times out. Its caller then treats a zero return as a short successful read, and partial reads for full 32-byte blocks can make the tail copy use a fixed block offset rather than the amount already produced. Return the poll error when no data has been read, preserve partial positive returns after some data is available, stop the generator on all collection exits, and append tail bytes at the current output count. | ||||
| CVE-2026-93156 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: rk3288 - fail ahash requests on HASH idle timeout rk_hash_run() waits for RK_CRYPTO_HASH_STS to become idle after the final DMA transfer, but ignores the poll result. If the hash engine never becomes idle, the driver still reads the digest registers and finalizes the request with the previous success value. Store the poll result and finalize the request with the timeout error before reading the digest registers. | ||||
| CVE-2026-93155 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: keembay - Fix AEAD unregister count in error path register_aes_algs() registers the AEAD algorithms before registering the skcipher algorithms. If skcipher registration fails, the function unwinds the earlier AEAD registration with crypto_engine_unregister_aeads(), but it passes ARRAY_SIZE(algs), which is the skcipher table size. Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper iterates over the same table that was registered. Also clarify the nearby comment: the crypto registration helpers clean up algorithms registered within the same call, while this function must still unwind earlier successful registration steps. | ||||
| CVE-2026-93154 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Add refcounting to user ring MRs Prevent userspace from deregistering the MRs that back QP/CQ/SRQ rings by bumping the MR's refcount upon association. | ||||
| CVE-2026-93153 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/bng_re: return a timeout when firmware responses stall __wait_for_resp() documents that it returns a non-zero error when a firmware command does not complete, and bng_re_rcfw_send_message() already marks the firmware as stalled when the helper returns -ENODEV. However, the helper ignores wait_event_timeout() expiry. If the response slot remains in use after the timeout and after the polled CREQ service attempt, the loop starts another full timeout period and can repeat forever. Return -ENODEV after a timed out wait that still has no response. The existing caller then marks FIRMWARE_STALL_DETECTED and returns -ETIMEDOUT to the command issuer. | ||||
| CVE-2026-93152 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: nvme-apple: Use acquire/release for queue enabled state apple_nvme_init_queue() initializes queue state and then marks the queue enabled. The interrupt and request paths check enabled before using that queue state. The old wmb() after WRITE_ONCE(enabled, true) does not publish the earlier initialization before enabled becomes visible. Use a release store when enabling the queue and acquire loads when testing it. Although the shutdown-side enabled accesses are not used for publishing queue initialization, use helpers for them as well for consistency. | ||||
| CVE-2026-93151 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: nvmet-rdma: fix response resource leak on queue teardown When an nvme target with rdma transport is removed while I/Os are in flight, a response can be posted but its send completion is never delivered before the connection is torn down. As a result nvmet_rdma_send_done() and nvmet_rdma_release_rsp() are never called for the response, and this leaks the allocated RDMA read/write context and request SGLs. These leaks are recreated by running blktests nvme/061 with the rdma transport and the siw driver. Kernel kmemleak feature reports them as follows: unreferenced object 0xffff88812bc490c0 (size 32): comm "kworker/2:1H", pid 409, jiffies 4307744490 backtrace (crc 89afd339): __kmalloc_noprof+0x5f9/0x890 sgl_alloc_order+0x7b/0x380 nvmet_req_alloc_sgls+0x290/0x4f0 [nvmet] nvmet_rdma_map_sgl_keyed+0x241/0x12e0 [nvmet_rdma] nvmet_rdma_handle_command+0x73e/0xb80 [nvmet_rdma] __ib_process_cq+0x149/0x4c0 [ib_core] ib_cq_poll_work+0x49/0x160 [ib_core] process_one_work+0x8b2/0x1640 worker_thread+0x5fd/0xfe0 kthread+0x367/0x460 ret_from_fork+0x655/0x9d0 ret_from_fork_asm+0x1a/0x30 unreferenced object 0xffff88814bd05e80 (size 64): comm "kworker/3:1H", pid 148, jiffies 4295195428 backtrace (crc e35510cb): __kmalloc_noprof+0x5f9/0x890 rdma_rw_ctx_init+0x333/0x1fa0 [ib_core] nvmet_rdma_map_sgl_keyed+0x5c8/0x12e0 [nvmet_rdma] nvmet_rdma_handle_command+0x73e/0xb80 [nvmet_rdma] __ib_process_cq+0x149/0x4c0 [ib_core] ib_cq_poll_work+0x49/0x160 [ib_core] process_one_work+0x8b2/0x1640 worker_thread+0x5fd/0xfe0 kthread+0x367/0x460 ret_from_fork+0x655/0x9d0 ret_from_fork_asm+0x1a/0x30 To avoid the memory leaks, reclaim the memory of the in-flight responses when the queue QP is torn down. Call nvmet_rdma_free_rsp_resources() that frees up the RDMA read/write context and the request SGLs of such responses. | ||||
| CVE-2026-93150 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Make nr_deadline_tasks an atomic_t The nr_deadline_tasks variable in the cpuset structure was introduced by commit 6c24849f5515 ("sched/cpuset: Keep track of SCHED_DEADLINE task in cpusets"). It is reported by sashiko [1] that nr_deadline_tasks can currently be modified by inc_dl_tasks_cs() under rq->lock and by cpuset_attach() under cpuset_mutex. So if both updates happen simultaneously, the nr_deadline_tasks variable can be corrupted leading to incorrect operations down the road. Fix that by changing its type to atomic_t so that nr_deadline_tasks are always atomically updated. This fix patch is a low hanging fruit. It can handle some of the races between a concurrent sched_setscheduler() and cpuset_can_attach()/cpuset_attach() calls, but not all of them like the other issue raised by sashiko [2]. This will be handled hopefully in a future follow up patch.

| CVE-2026-93149 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211_hwsim: avoid NULL skb in stop queue drain mac80211_hwsim_stop() drops any frames left in data->pending. The loop currently checks skb_queue_empty() and then dequeues separately. That split is racy with TX status handling, which can remove a pending frame under the queue lock. If the last entry is removed after the empty check, skb_dequeue() returns NULL and the stop path passes that NULL skb to ieee80211_free_txskb(). Use skb_dequeue() as the loop condition instead. The dequeue result is the object that stop owns and frees, and a concurrent status completion that empties the queue simply makes the loop terminate. | ||||
| CVE-2026-93148 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reject MEM_ALLOC BTF accesses past object bounds BTF struct walks relax the struct-size check for accesses through a trailing flexible array. That is valid for ordinary BTF type walking, but PTR_TO_BTF_ID | MEM_ALLOC values point to objects allocated with the static BTF type size. When walking a MEM_ALLOC object, reject the access before applying the flexible-array relaxation if the access range extends past the struct size. Apply the same policy to struct ID matching so kfunc and kptr type checks do not walk past the allocated object bounds either. | ||||
| CVE-2026-93147 | 1 Linux | 1 Linux Kernel | 2026-09-17 | N/A |
