CVE-2026-19519

Summary

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.

Affected Software

Weaknesses

• CWE-617: Reachable Assertion

Workarounds

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.
