This can allow malicio...

CVE-2026-35376

A TOCTOU vulnerability exists in the chcon utility of uutils coreutils during recursive operations. The code uses a fresh path lookup (fts_accpath) to resolve targets instead of binding traversal and label application to the directory state encountered during traversal, and the operations are not...

CVE-2026-35340

The CVE-2026-35340 issue affects the uutils coreutils chown and chgrp via the ChownExecutor. In recursive operations, the utilities return an exit code based solely on the last processed file; if earlier ownership/group changes failed due to permissions, they may still report success (0). This ca...

CVE-2026-35348

CVE-2026-35348 affects the sort utility in uutils coreutils. Using --files0-from with inputs containing non-UTF-8 filenames triggers a process panic because the implementation enforces UTF-8 and uses expect(), causing a crash on valid but non-UTF-8 paths. This diverges from GNU sort, which treats...

CVE-2026-35356

CVE-2026-35356 describes a TOCTOU vulnerability in the install utility of the uutils coreutils when using -D.
