  "summary": "CVE-2026-107888 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.",
  "title": "OpenPrinting CUPS before 2.4.20 contains a NULL pointer dereference in cupsdCheckJobs() when a job marked job-held-on-create refers to a temporary printer that has been automatically deleted. Temporary-printer cleanup can remove the destination without canceling its held jobs, and the scheduler dereferences the NULL result of cupsdFindDest() while checking holding_new_jobs. This terminates cupsd and interrupts all queues managed by that process. In some plausible scenarios, an unprivileged submission can trigger this.",
