https://notcve.org/view.php?id=CVE-2022-49288
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent prealloc proc writes We have no protection against concurrent PCM buffer preallocation changes via proc files, and it may potentially lead to UAF or some weird problem. This patch applies the PCM open_mutex to the proc write operation for avoiding the racy proc writes and the PCM stream open (and further operations). • https://git.kernel.org/stable/c/e7786c445bb67a9a6e64f66ebd6b7215b153ff7d •

In this conversion, tpm2_del_space() was missed. This didn't matter much because it's usually called closely after a converted operation, so there's only a very tiny race window... • https://git.kernel.org/stable/c/5b1d2561a03e534064b51c50c774657833d3d2cf •

CVE-2022-49281 – cifs: fix handlecache and multiuser

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: cifs: fix handlecache and multiuser In multiuser each individual user has their own tcon structure for the share and thus their own handle for a cached directory. When we umount such a share we much make sure to release the pinned down dentry for each such tcon and not just the master tcon. Otherwise we will get nasty warnings on umount that dentries are still in use: [ 3459.590047] BUG: Dentry 00000000115c6f41{i=12000000019d95,n=/} still i... • https://git.kernel.org/stable/c/2fafbc198613823943c106d1ec9b516da692059f •
