CVE-2024-57946 – virtio-blk: don't keep queue frozen during system suspend
https://notcve.org/view.php?id=CVE-2024-57946
21 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: virtio-blk: don't keep queue frozen during system suspend Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's PM callbacks. And the motivation is to drain inflight IOs before suspending. block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bio_queue_enter() may run into deadlock if t... • https://git.kernel.org/stable/c/d738f3215bb4f88911ff4579780a44960c8e0ca5 •

CVE-2024-57924 – fs: relax assertions on failure to encode file handles

19 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: fs: relax assertions on failure to encode file handles Encoding file handles is usually performed by a filesystem >encode_fh() method that may fail for various reasons. The legacy users of exportfs_encode_fh(), namely, nfsd and name_to_handle_at(2) syscall are ready to cope with the possibility of failure to encode a file handle. There are a few other users of exportfs_encode_{fh,fid}() that currently have a WARN_ON() assertion when ->encod... • https://git.kernel.org/stable/c/f47c834a9131ae64bee3c462f4e610c67b0a000f •

CVE-2024-57899 – wifi: mac80211: fix mbss changed flags corruption on 32 bit systems

15 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix mbss changed flags corruption on 32 bit systems On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding.
