CVE-2026-16460 · Bootc: ostree: bootc/ostree: staged deployments not revalidated against container signature policy before finalization

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
