✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: This CVE requires same-user access to the p11-kit RPC Unix domain socket (/run/user/<uid>/p11-kit/pkcs11-*). Any process running as the socket-owning user can trigger the crash without further authentication. If p11-kit is managed via systemd --user, ensure `Restart=on-failure` is set in the unit file so that a crash is automatically recovered without manual intervention. Red Hat recommends updating p11-kit to version 0.26.3 or later, which introduces a recursion depth limit in the RPC attribute parsing and fully addresses this flaw.
