{"schemaVersion":3,"id":"CVE-2026-107888","aliases":["DEBIAN-CVE-2026-107888","UBUNTU-CVE-2026-107888"],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-09T04:06:55.424Z","modified":"2026-10-15T18:09:56.261Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.1,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
