CVE-2026-31694

Summary: CVE-2026-31694 fixes a Linux kernel FUSE directory-entry handling flaw. A malicious FUSE server could cause a 24-byte overflow by returning a dirent whose serialized size (based on namelen) exceeds a single PAGE_SIZE. The bug arises in fuse_add_dirent_to_cache(), which previously only ch...
