✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: As a workaround, use 'restorecon -R /' directly instead of 'fixfiles relabel' or 'fixfiles restore' to perform filesystem relabeling. This avoids the vulnerable /tmp-specific find+chcon code path entirely. Note that this skips the /tmp cleanup logic, but on modern systems where /tmp is mounted as tmpfs, this cleanup is unnecessary as tmpfs cannot retain files from a prior boot.
