Cups: null pointer dereference via embedded job ticket comments allows remote denial of service
CVE-2026-107655 is fixed in 15 products on 1 platform, first by ALAS2023-2026-3415, released November 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in CUPS. When processing embedded job ticket comments within documents, the service improperly handles specific IPP attributes, causing an unhandled null pointer dereference. An unauthenticated attacker permitted to submit jobs to a shared printer queue can send a crafted Internet Printing Protocol (IPP) request to crash the print daemon, resulting in a temporary Denial of Service (DoS) for all printing services.
