CVE-2026-16254

Estado: Pendiente de análisisMedia (4.3)—

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.
