CVE-2026-88264

5.6 mediumEPSS 0.1%

Medium (5.6). EPSS 0.1% chance of exploitation in the next 30 days.

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.
