FreeBSD-SA-26:13.exec documents a local privilege escalation via execve() on FreeBSD 14.2 and 13.4. The flaw allows unprivileged users to bypass security restrictions by manipulating environment variables during binary execution, granting root access on affected systems. Patches are available in FreeBSD 14.2-RELEASE-p2 and 13.4-RELEASE-p3. Upgrade immediately to close this vector.
