CVE-2023-5557Public exploitNetwork attack vector

Code execution via incomplete seccomp sandbox

Published Oct 13, 2023 · Updated Nov 20, 2025

Protection mechanism failure in tracker-miners on Red Hat Enterprise Linux 8 and 9 allows attackers to escape the seccomp sandbox. The tracker-extract seccomp policy permits an undisclosed syscall path that fails to confine code already running after a separate compromise. Exploitation requires user interaction with a malicious file and prior compromise of tracker-extract; escaped code runs with the current user's privileges.
