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.","epss":{"date":"2026-11-05","percentile":0.01933,"score":0.00121},"exploits":[],"kev":null,"metrics":[{"score":5.6,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:N","version":"3.1"}],"modifiedAt":1793927588271,"publishedAt":1789029636527,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:71668"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-88264"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2531223"},{"source":"CNA: redhat","tags":[],"url":"https://github.com/containers/crun/"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Always mount /dev (Podman/crun default).
