CVE-2026-82430: Fts Traversal Pathname Chmod Toctou
Pathname-based permission or ownership operations (chmod, chown, lchown) on FTS traversal entries (fts_path or fts_accpath) are vulnerable to TOCTOU symlink races. An attacker with write access to the traversed directory can replace the entry with a symlink before chmod/chown runs, leading to unauthorized modification of arbitrary files. Instead, open the fi
