CVE-2023-0229Network attack vector

Authenticated seccomp bypass via unchecked pod profile

Published Jan 25, 2023 · Updated Apr 1, 2025

Improper input validation in Red Hat OpenShift Container Platform 4.11 and 4.12 allows remote authenticated users to disable pod seccomp. The restricted-v2 SCC admission path accepts a pod's unconfined seccomp profile instead of enforcing its runtime/default policy. A user who can create or modify pods can remove the syscall filter from controlled workloads, weakening their intended isolation from the Linux kernel.
