{"id":"UBUNTU-CVE-2026-88264","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":"2026-09-16T14:03:21.877523345Z","published":"2026-09-10T09:17:00Z","upstream":["CVE-2026-88264"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-88264"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-88264"}],"affected":[{"package":{"name":"crun","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/crun?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.5+dfsg-1","0.10.6+dfsg-1","0.11+dfsg-1","0.12+dfsg-1","0.12.1+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.12.1+dfsg-1","binary_name":"crun"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-88264.json"}},{"package":{"name":"crun","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/crun?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17+dfsg-1","0.17+dfsg-1.1","0.17+dfsg-1.1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"crun","binary_version":"0.17+dfsg-1.1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-88264.json"}},{"package":{"name":"crun","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/crun?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.5-1","1.11-1","1.11.1-1","1.12-1","1.13-1","1.14-1","1.14.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.14.1-1","binary_name":"crun"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-88264.json"}},{"package":{"name":"crun","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/crun?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.21-1ubuntu2","1.21-1ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"crun","binary_version":"1.21-1ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"Ubuntu","score":"medium"}]}
