26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: f2fs: fix dereference of stale list iterator after loop body The list iterator variable will be a bogus pointer if no break was hit. Dereferencing it (cur->page in this case) could load an out-of-bounds/undefined value making it unsafe to use that in the comparision to determine if the specific element was found. Since 'cur->page' *can* be out-ouf-bounds it cannot be guaranteed that by chance (or intention of an attacker) it matches the val... • https://git.kernel.org/stable/c/8c242db9b8c01b252290e23827163787f07e01d1 •
