CVE-2026-35350

6.6 medium SSVC exploitation: poc Analyzed
NVD · CVE.org

The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining original privileged bits, creating unexpected privileged executables that violate local security policies. This differs from GNU cp, which clears these bits when ownership cannot be preserved.
