As a result, a user-requested ASLR disable was still in effect at the point where the base address was chosen.\n\nAn unprivileged local user can disable ASLR for a setuid PIE binary by calling procctl(2) before execve(2). This makes exploitation of any separate memory corruption vulnerability in that binary significantly easier."}], "lastModified": "2026-06-27T10:16:37.007", "sourceIdentifier": "secteam@freebsd.org"}
