CVE-2025-22079 is a high-severity vulnerability in the Linux kernel's OCFS2 filesystem driver. It involves improper validation of the l_tree_depth field, which is a 16-bit value but should be limited by OCFS2_MAX_PATH_DEPTH. Without proper validation, an out-of-bounds access can occur when reading from a corrupted mounted disk, potentially leading to a denial of service or other impacts.
