Medium [CVE-2026-19519] denial of service via unchecked type assertion in RPM header parser
CVE-2026-19519Source published Source updated
A flaw was found in claircore's RPM package scanner. Crafted RPM header data in a container layer can cause an unchecked type assertion to panic the scanner. The panic is not recovered, causing the Clair indexer process to crash, leading to a denial of service. Red Hat Quay Clair and RHACS Scanner V4 deployments run the indexer as multiple OpenShift pods (default replica count >= 2) with automatic kubelet restart on crash. An unrecovered panic in claircore RPM header parsing terminates one indexer pod; the remaining replicas and automatic pod restart limit the impact to a temporary interruption of image indexing rather than a lasting registry or scanning outage. Availability impact is therefore Low (A:L), consistent with the precedent claircore panic-DoS flaw CVE-2026-16254 (apk parser…

- Source-reported affected versions
- Affected-version details not available in this record.
- Source-reported fixed versions
- No fixed-version detail extracted. This does not mean no fix exists.
- Mitigation guidance
- Where possible, configure the indexer to run scanner workloads in isolated processes or containers so that a single scanner panic cannot terminate the shared indexer. Alternatively, deploy multiple indexer replicas behind a load balancer to reduce the blast radius of a single-process crash.
