https://notcve.org/view.php?id=CVE-2023-52737
21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: lock the inode in shared mode before starting fiemap Currently fiemap does not take the inode's lock (VFS lock), it only locks a file range in the inode's io tree. This however can lead to a deadlock if we have a concurrent fsync on the file and fiemap code triggers a fault when accessing the user space buffer with fiemap_fill_next_extent(). The deadlock happens on the inode's i_mmap_lock semaphore, which is taken both by fsync and b... • https://git.kernel.org/stable/c/d8c594da79bc0244e610a70594e824a401802be1 •

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Do not unset preset when cleaning up codec Several functions that take part in codec's initialization and removal are re-used by ASoC codec drivers implementations. Drivers mimic the behavior of hda_codec_driver_probe/remove() found in sound/pci/hda/hda_bind.c with their component->probe/remove() instead. One of the reasons for that is the expectation of snd_hda_codec_device_new() to receive a valid pointer to an instance of stru... • https://git.kernel.org/stable/c/7fc4e7191eae9d9325511e03deadfdb2224914f8 •

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: s390/decompressor: specify __decompress() buf len to avoid overflow Historically calls to __decompress() didn't specify "out_len" parameter on many architectures including s390, expecting that no writes beyond uncompressed kernel image are performed.
