CVE-2026-62146
A trust-boundary flaw in CRI-O's sandbox state persistence allows attacker-influenced pod metadata to overwrite CRI-O's own reserved sandbox bookkeeping; once reloaded as trusted after a restart, a later container recreate in that sandbox can expose a host-side runtime-management resource inside the container, enabling container escape.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.11%
- Percentil entre todas las CVEs puntuadas: 1
- Fecha de la puntuación: 5/10/2026

🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation85 % - Impacto principal
T1548.004Elevated Execution with Promptprivilege escalation80 % - Impacto secundario
T1005Data from Local Systemcollection70 % - Impacto secundario
T1611Escape to Hostprivilege escalation75 %
Vulnerabilidad de escalada de privilegios local (AV:L, PR:L) en CRI-O que permite escape de contenedor mediante sobrescritura de metadatos de sandbox persistidos. Expone recursos del runtime del host al contenedor, permitiendo acceso no autorizado y control sobre la infraestructura de gestión de run
