Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35376[0]:
| A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the
| chcon utility of uutils coreutils during recursive operations. The
| implementation resolves recursive targets using a fresh path lookup
| (via fts_accpath) rather than binding the traversal and label
| application to the specific directory state encountered during
| traversal. Because these operations are not anchored to file
| descriptors, a local attacker with write access to a directory tree
| can exploit timing-sensitive rename or symbolic link races to
| redirect a privileged recursive relabeling operation to unintended
| files or directories. This vulnerability breaks the hardening
| expectations for SELinux administration workflows and can lead to
| the unauthorized modification of security labels on sensitive system
| objects.
