27 Sep 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: don't BUG_ON on ENOMEM from btrfs_lookup_extent_info() in walk_down_proc() We handle errors here properly, ENOMEM isn't fatal, return the error. Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service or possibly execute arbitrary code.

27 Sep 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: clean up our handling of refs == 0 in snapshot delete In reada we BUG_ON(refs == 0), which could be unkind since we aren't holding a lock on the extent leaf and thus could get a transient incorrect answer. In walk_down_proc we also BUG_ON(refs == 0), which could happen if we have extent tree corruption. Change that to return -EUCLEAN. In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN... • https://git.kernel.org/stable/c/2c47e605a91dde6b0514f689645e7ab336c8592a •
