CVSS 7.4 (high) · published 2026-10-19
A flaw was found in bootc and ostree. Already-staged deployments are finalized without revalidating the deployment's container image against the current containers signature policy. Unsigned OS content staged under a prior permissive policy can remain bootable after policy is hardened to reject unsigned images, leading to full host compromise on reboot.
Weakness: CWE-345
Source: NVD CVE-2026-16460
