OpenPrinting

A local attacker can exploit a vulnerability in the Common Unix Printing System (CUPS) to cause a denial-of-service condition affecting the printing service.

A vulnerability in the cups-browsed service allows a local attacker to achieve arbitrary code execution via malicious print queue discovery packets.

A high-severity denial of service vulnerability, CVE-2026-64611, exists in the `cfIEEE1284NormalizeMakeModel()` function of libcupsfilters, allowing a network-adjacent attacker to cause sustained CPU consumption and system unresponsiveness by broadcasting a specially crafted printer advertisement with an empty model field in the IEEE-1284 device ID.

A high-severity denial-of-service vulnerability (CVE-2026-64612) exists in libcupsfilters and cups-filters, allowing an unauthenticated attacker to cause the CUPS image filter process to abort by submitting a specially crafted PNG print job, leading to service disruption.
