Description OSIDB Bzimport 2025-10-17 14:51:59 UTC 
A flaw was found in runc. CVE-2025-52565 is very similar in concept and application toCVE-2025-31133, except that it exploits a flaw in /dev/console
bind-mounts. When creating the /dev/console bind-mount (to /dev/pts/$n), if an attacker replaces /dev/pts/$n with a symlink then runc will bind-mount the symlink target over /dev/console.
