CVE-2026-61626

A flaw was found in libass. When handling subtitle streams, the library's event pruning mechanism fails to properly validate negative Matroska ReadOrder values. An attacker who provides a specially crafted media stream to an application using libass can trigger memory corruption, resulting in an...
