GHSA-R9HW-MJ3W-PHCQ mknod: Device nodes created mislabeled on SELinux, with broken cleanup (remove_dir on a node)

uutils calls mknod before setting the SELinux context GNU uses setfscreatecon first, labeling atomically. If setselinuxsecuritycontext fails, cleanup uses std::fs::removedir, which cannot remove device nodes or FIFOs, leaving the mislabeled node behind. Impact: on SELinux-enforcing systems the no...

CVE-2026-35358

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...

CVE-2026-35361

The CVE-2026-35361 issue affects the mknod utility in uutils coreutils. It describes non-atomic handling of security labels for created device nodes: mknod creates the nodes before applying the SELinux context, and on labeling failure attempts cleanup via std::fs::remove_dir, which cannot remove ...
