https://notcve.org/view.php?id=CVE-2024-26654
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 be rescheduled in the timer handler. As a result, the UAF bug will happen. The racy situation is shown below: (Thread 1) | (Thread 2) snd_aicapcm_pcm_close() | • https://git.kernel.org/stable/c/198de43d758ca2700e2b52b49c0b189b4931466c https://git.kernel.org/stable/c/eeb2a2ca0b8de7e1c66afaf719529154e7dc60b2 https://git.kernel.org/stable/c/4206ad65a0ee76920041a755bd3c17c6ba59bba2 https://git.kernel.org/stable/c/aa39e6878f61f50892ee2dd9d2176f72020be845 https://git.kernel.org/stable/c/8c990221681688da34295d6d76cc2f5b963e83f5 https://git.kernel.org/stable/c/9d66ae0e7bb78b54e1e0525456c6b54e1d132046 https://git.kernel.org/stable/c/61d4787692c1fccdc268ffa7a891f9c149f50901 https://git.kernel.org/stable/c/e955e8a7f38a856fc6534ba4e6bffd4d5 •

https://notcve.org/view.php?id=CVE-2023-52629
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. The details are shown below: (cpu 0) | (cpu 1) switch_drv_remove() | flush_work() | . • https://git.kernel.org/stable/c/9f5e8eee5cfe1328660c71812d87c2a67bda389f https://git.kernel.org/stable/c/610dbd8ac271aa36080aac50b928d700ee3fe4de https://git.kernel.org/stable/c/246f80a0b17f8f582b2c0996db02998239057c65 • CWE-416: Use After Free •
