In the Linux kernel, the following vulnerability has been resolved: io_uring/rsrc: don't lock while !TASK_RUNNING There is a report of io_rsrc_ref_quiesce() locking a mutex while not TASK_RUNNING, which is due to forgetting restoring the state back after io_run_task_work_sig() and attempts to break out of the waiting loop. do not call blocking ops when !TASK_RUNNING; state=1 set at [<ffffffff815d2494>] prepare_to_wait+0xa4/0x380 kernel/sched/wait.c:237 WARNING: CPU: 2 PID: 397056 at kernel/sched/core.c:10099 __might_sleep+0x114/0x160 kernel/sched/core.c:10099 RIP: 0010:__might_sleep+0x114/0x160 kernel/sched/core.c:10099 Call Trace: <TASK> __mutex_lock_common kernel/locking/mutex.c:585 [inline] __mutex_lock+0xb4/0x940 kernel/locking/mutex.c:752 io_rsrc_ref_quiesce+0x590/0x940 io_uring/rsrc.c:253 io_sqe_buffers_unregister+0xa2/0x340 io_uring/rsrc.c:799 __io_uring_register io_uring/register.c:424 [inline] __do_sys_io_uring_register+0x5b9/0x2400 io_uring/register.c:613 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xd8/0x270 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x6f/0x77 • https://git.kernel.org/stable/c/4ea15b56f0810f0d8795d475db1bb74b3a7c1b2f https://git.kernel.org/stable/c/0c9df3df0c888d9ec8d11a68474a4aa04d371cff https://git.kernel.org/stable/c/4429c6c77e176a4c5aa7a3bbd1632f9fc0582518 https://git.kernel.org/stable/c/54559642b96116b45e4b5ca7fd9f7835b8561272 •

https://notcve.org/view.php?id=CVE-2024-40921
In the Linux kernel, the following vulnerability has been resolved: net: bridge: mst: pass vlan group directly to br_mst_vlan_set_state Pass the already obtained vlan group pointer to br_mst_vlan_set_state() instead of dereferencing it again. Each caller has already correctly dereferenced it for their context. This change is required for the following suspicious RCU dereference fix. No functional changes intended. • https://git.kernel.org/stable/c/8ca9a750fc711911ef616ceb627d07357b04545e https://git.kernel.org/stable/c/4488617e5e995a09abe4d81add5fb165674edb59 https://git.kernel.org/stable/c/e43dd2b1ec746e105b7db5f9ad6ef14685a615a4 https://git.kernel.org/stable/c/a2b01e65d9ba8af2bb086d3b7288ca53a07249ac https://git.kernel.org/stable/c/09f4337c27f5bdeb8646a6db91488cc2f7d537ff https://git.kernel.org/stable/c/a6cc9e9a651b9861efa068c164ee62dfba68c6ca https://git.kernel.org/stable/c/d2dc02775fc0c4eacaee833a0637e5958884a8e5 https://git.kernel.org/stable/c/36c92936e868601fa1f43da6758cf5580 •

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-40919 – bnxt_en: Adjust logging of firmware messages in case of released token in __hwrm_send()
https://notcve.org/view.php?id=CVE-2024-40919
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Adjust logging of firmware messages in case of released token in __hwrm_send() In case of token is released due to token->state == BNXT_HWRM_DEFERRED, released token (set to NULL) is used in log messages. This issue is expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But this error code is returned by recent firmware. So some firmware may not return it. This may lead to NULL pointer dereference. Adjust this issue by adding token pointer check.

CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-40918 – parisc: Try to fix random segmentation faults in package builds
https://notcve.org/view.php?id=CVE-2024-40918
In the Linux kernel, the following vulnerability has been resolved: parisc: Try to fix random segmentation faults in package builds PA-RISC systems with PA8800 and PA8900 processors have had problems with random segmentation faults for many years. Systems with earlier processors are much more stable. Systems with PA8800 and PA8900 processors have a large L2 cache which needs per page flushing for decent performance when a large range is flushed. The combined cache in these systems is also more sensitive to non-equivalent aliases than the caches in earlier systems. The majority of random segmentation faults that I have looked at appear to be memory corruption in memory allocated using mmap and malloc. My first attempt at fixing the random faults didn't work. On reviewing the cache code, I realized that there were two issues which the existing code didn't handle correctly. Both relate to cache move-in. • https://git.kernel.org/stable/c/5bf196f1936bf93df31112fbdfb78c03537c07b0 https://git.kernel.org/stable/c/d66f2607d89f760cdffed88b22f309c895a2af20 https://git.kernel.org/stable/c/72d95924ee35c8cd16ef52f912483ee938a34d49 •
