|---|---|---|---|
| 2024-09-04 | CVE-2024-44954 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: line6: Fix racy access to midibuf There can be concurrent accesses to line6 midibuf from both the URB completion callback and the rawmidi API access. | 4.7 |
| 2024-09-04 | CVE-2024-44955 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Don't refer to dc_sink in is_dsc_need_re_compute [Why] When unplug one of monitors connected after mst hub, encounter null pointer dereference. It's due to dc_sink get released immediately in early_unregister() or detect_ctx(). | 5.5 |
| 2024-09-04 | CVE-2024-44956 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/xe/preempt_fence: enlarge the fence critical section It is really easy to introduce subtle deadlocks in preempt_fence_work_func() since we operate on single global ordered-wq for signalling our preempt fences behind the scenes, so even though we signal a particular fence, everything in the callback should be in the fence critical section, since blocking in the callback will prevent other published fences from signalling. | 5.5 |
| 2024-09-04 | CVE-2024-44957 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xen: privcmd: Switch from mutex to spinlock for irqfds irqfd_wakeup() gets EPOLLHUP, when it is called by eventfd_release() by way of wake_up_poll(&ctx->wqh, EPOLLHUP), which gets called under spin_lock_irqsave(). | 5.5 |
| 2024-09-04 | CVE-2024-44958 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: sched/smt: Fix unbalance sched_smt_present dec/inc I got the following warn report while doing stress test: jump label: negative count! WARNING: CPU: 3 PID: 38 at kernel/jump_label.c:263 static_key_slow_try_dec+0x9d/0xb0 Call Trace: <TASK> __static_key_slow_dec_cpuslocked+0x16/0x70 sched_cpu_deactivate+0x26e/0x2a0 cpuhp_invoke_callback+0x3ad/0x10d0 cpuhp_thread_fun+0x3f5/0x680 smpboot_thread_fn+0x56d/0x8d0 kthread+0x309/0x400 ret_from_fork+0x41/0x70 ret_from_fork_asm+0x1b/0x30 </TASK> Because when cpuset_cpu_inactive() fails in sched_cpu_deactivate(), the cpu offline failed, but sched_smt_present is decremented before calling sched_cpu_deactivate(), it leads to unbalanced dec/inc, so fix it by incrementing sched_smt_present in the error path. | 5.5 |
| 2024-09-04 | CVE-2024-44959 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tracefs: Use generic inode RCU for synchronizing freeing With structure layout randomization enabled for 'struct inode' we need to avoid overlapping any of the RCU-used / initialized-only-once members, e.g. | 5.5 |
| 2024-09-04 | CVE-2024-44960 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: usb: gadget: core: Check for unset descriptor Make sure the descriptor has been set before looking at maxpacket. This fixes a null pointer panic in this case. This may happen if the gadget doesn't properly set up the endpoint for the current speed, or the gadget descriptors are malformed and the descriptor for the speed/endpoint are not found. No current gadget driver is known to have this problem, but this may cause a hard-to-find bug during development of new gadgets. | 5.5 |
| 2024-09-04 | CVE-2024-44961 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Forward soft recovery errors to userspace As we discussed before[1], soft recovery should be forwarded to userspace, or we can get into a really bad state where apps will keep submitting hanging command buffers cascading us to a hard reset. 1: https://lore.kernel.org/all/[email protected]/ (cherry picked from commit 434967aadbbbe3ad9103cc29e9a327de20fdba01) | 5.5 |
| 2024-09-04 | CVE-2024-44962 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading When unload the btnxpuart driver, its associated timer will be deleted. If the timer happens to be modified at this moment, it leads to the kernel call this timer even after the driver unloaded, resulting in kernel panic. Use timer_shutdown_sync() instead of del_timer_sync() to prevent rearming. panic log: Internal error: Oops: 0000000086000007 [#1] PREEMPT SMP Modules linked in: algif_hash algif_skcipher af_alg moal(O) mlan(O) crct10dif_ce polyval_ce polyval_generic snd_soc_imx_card snd_soc_fsl_asoc_card snd_soc_imx_audmux mxc_jpeg_encdec v4l2_jpeg snd_soc_wm8962 snd_soc_fsl_micfil snd_soc_fsl_sai flexcan snd_soc_fsl_utils ap130x rpmsg_ctrl imx_pcm_dma can_dev rpmsg_char pwm_fan fuse [last unloaded: btnxpuart] CPU: 5 PID: 723 Comm: memtester Tainted: G O 6.6.23-lts-next-06207-g4aef2658ac28 #1 Hardware name: NXP i.MX95 19X19 board (DT) pstate: 20400009 (nzCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : 0xffff80007a2cf464 lr : call_timer_fn.isra.0+0x24/0x80 ...
