• Severity: high (CVSS 7.8 v3.1)

• Published: 2026-09-30 · updated 2026-10-30
• Weakness: CWE-501

Description

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.
