CVE-2026-64612 is a denial-of-service vulnerability in libcupsfilters and cups-filters. The flaw occurs in the PNG image reading path, where the code creates a libpng reader without installing an error recovery handler. When the CUPS image filter processes a malformed PNG file, libpng error handling can cause the filter process to abort instead of recovering gracefully. An attacker can trigger this condition by submitting a specially crafted PNG print job to a vulnerable printing workflow.
