CVE-2022-49343 – ext4: avoid cycles in directory h-tree
https://notcve.org/view.php?id=CVE-2022-49343
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: ext4: avoid cycles in directory h-tree A maliciously corrupted filesystem can contain cycles in the h-tree stored inside a directory. That can easily lead to the kernel corrupting tree nodes that were already verified under its hands while doing a node split and consequently accessing unallocated memory. Fix the problem by verifying traversed block numbers are unique.

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: bcache: avoid journal no-space deadlock by reserving 1 journal bucket The journal no-space deadlock was reported time to time. Such deadlock can happen in the following situation. When all journal buckets are fully filled by active jset with heavy write I/O load, the cache set registration (after a reboot) will load all active jsets and inserting them into the btree again (which is called journal replay). If a journaled bkey is inserted int... • https://git.kernel.org/stable/c/59afd4f287900c8187e968a4153ed35e6b48efce •
