{"id":"CVE-2026-107888","published":"2026-10-09T05:16:44.407","lastModified":"2026-10-09T16:37:45.710","description":"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.","cvssScore":5.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-476"],"vendors":[],"products":[],"references":[{"url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-qqm8-4q5h-jg55","tags":[]}],"exploitRefs":[{"url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-qqm8-4q5h-jg55","tags":[]}],"hasPoc":true,"ai":null}
