{"id":"CVE-2026-88264","summary":"Crun: crun: /dev/console symlink follow allows root-owned file creation outside the rootfs","details":"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.","modified":"2026-09-27T03:30:57.309957636Z","published":"2026-09-10T08:40:36.527Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88264.json","cna_assigner":"redhat","cwe_ids":["CWE-59"]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"WEB","url":"https://github.com/containers/crun/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:71668"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-88264"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88264.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88264"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2531223"},{"type":"PACKAGE","url":"https://github.com/containers/crun"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/containers/crun","events":[{"introduced":"0"},{"last_affected":"f0d911de5587342cfeb16473bf32ecdfeaf25957"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.29.1"}],"source":"AFFECTED_FIELD"}}],"versions":["1.29.1","1.27","1.5","1.0","0.12.1","0.10.6","0.10.5","0.10.4","0.10.3","0.10.2","0.10.1","0.10","0.9.1","0.9","0.8","0.7","0.6","0.5","0.4","v0.3","v0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-88264.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:N"}]}
