Medium [CVE-2026-16254] Denial of service via out-of-bounds slice in claircore's apk installed-database parser
CVE-2026-16254Source published Source updated
A flaw was found in claircore's apk package scanner. Malformed package-database data in a container layer can cause an out-of-bounds access that panics the scanner. If that panic is not recovered, the Clair indexer process can crash, leading to a denial of service. Red Hat Quay deployments, Clair typically runs as multiple OpenShift pods (default >=2, auto-restart). An unrecovered indexer panic terminates one Clair pod; remaining replicas and kubelet restart limit impact to a temporary interruption of vulnerability indexing, not a lasting Quay registry outage. Therefore Availability is Low (A:L). Red Hat severity: Moderate — CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Advanced Cluster Security 4; Red Hat Quay 3. Red Hat…
