How to fix?

Upgrade Alpine:3.24 crun to version 1.30.1-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream crun package and not the crun package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

A flaw was found in crun. When the container configuration does not give /dev a dedicated mount, terminal setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-mount fallback. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available yet.
