CVE-2026-16460 (CVSS 7.4)
NVD · officialPublished Oct 19, 2026Risk 23/100
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.
