CVE-2023-52633 – um: time-travel: fix time corruption
https://notcve.org/view.php?id=CVE-2023-52633
02 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: um: time-travel: fix time corruption In 'basic' time-travel mode (without =inf-cpu or =ext), we still get timer interrupts. These can happen at arbitrary points in time, i.e. while in timer_read(), which pushes time forward just a little bit. Then, if we happen to get the interrupt after calculating the new time to push to, but before actually finishing that, the interrupt will set the time to a value that's incompatible with the forward, a... • https://git.kernel.org/stable/c/0c7478a2da3f5fe106b4658338873d50c86ac7ab •

CVE-2024-26659 – xhci: handle isoc Babble and Buffer Overrun events properly
https://notcve.org/view.php?id=CVE-2024-26659
02 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: xhci: handle isoc Babble and Buffer Overrun events properly xHCI 4.9 explicitly forbids assuming that the xHC has released its ownership of a multi-TRB TD when it reports an error on one of the early TRBs. Yet the driver makes such assumption and releases the TD, allowing the remaining TRBs to be freed or overwritten by new TDs. The xHC should also report completion of the final TRB due to its IOC flag being set by us, regardless of prior e... • https://git.kernel.org/stable/c/696e4112e5c1ee61996198f0ebb6ca3fab55166e • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

02 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix use-after-free bug The bug can be triggered by sending a single amdgpu_gem_userptr_ioctl to the AMDGPU DRM driver on any ASICs with an invalid address and size. The bug was reported by Joonkyo Jung
CVE-2024-26654 – ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs

01 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs The dreamcastcard->timer could schedule the spu_dma_work and the spu_dma_work could also arm the dreamcastcard->timer. When the snd_pcm_substream is closing, the aica_channel will be deallocated. But it could still be dereferenced in the worker thread. The reason is that del_timer() will return directly regardless of whether the timer handler is running or not and the worker could... • https://git.kernel.org/stable/c/198de43d758ca2700e2b52b49c0b189b4931466c •
CVE-2023-52629 – sh: push-switch: Reorder cleanup operations to avoid use-after-free bug

29 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: sh: push-switch: Reorder cleanup operations to avoid use-after-free bug The original code puts flush_work() before timer_shutdown_sync() in switch_drv_remove(). Although we use flush_work() to stop the worker, it could be rescheduled in switch_timer(). As a result, a use-after-free bug can occur.

26 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: thermal: intel: hfi: Add syscore callbacks for system-wide PM The kernel allocates a memory buffer and provides its location to the hardware, which uses it to update the HFI table. This allocation occurs during boot and remains constant throughout runtime. When resuming from hibernation, the restore kernel allocates a second memory buffer and reprograms the HFI hardware with the new location as part of a normal boot. The location of the sec... • https://git.kernel.org/stable/c/28f010dc50df0f7987c04112114fcfa7e0803566 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •
