CVE-2025-68315

The CVE-2025-68315 issue affects the Linux kernel’s flash-friendly filesystem (F2FS). The vulnerability arises from a check gap in free_nid_list handling, risking corruption of the on-disk footer structures (footer.ino vs footer.nid) and enabling potential exploitation via corrupted NID entries. ...
