{"id":"CVE-2026-107888","details":"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.","aliases":["GHSA-qqm8-4q5h-jg55"],"modified":"2026-10-10T02:47:23.549921329Z","published":"2026-10-09T04:06:55.424Z","database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107888.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107888.json"},{"type":"ADVISORY","url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-qqm8-4q5h-jg55"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107888"},{"type":"PACKAGE","url":"https://github.com/OpenPrinting/cups"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openprinting/cups","events":[{"introduced":"0"},{"fixed":"ef80eeaea51430a055948240eea3f28ef5354edf"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"2.4.20"}]}}],"versions":["v2.4.19","v2.4.18","v2.4.17","v2.4.16","v2.4.15","v2.4.14","v2.4.13","v2.4.12","v2.4.11","v2.4.10","v2.4.9","v2.4.8","v2.4.7","v2.4.6","v2.4.5","v2.4.3","v2.4.4","v2.4.2","v2.4.1","v2.4.0","v2.4rc1","v2.4b1","v2.3.3op2","v2.3.3op1","v2.3.3","v2.3.1","v2.3.0","v2.3rc1","v2.3b8","v2.3b7","v2.3b6","v2.3b5","v2.3b4","v2.3b3","v2.3b2","v2.3b1","v2.2.6","v2.2.5","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2.0","v2.2rc1","v2.2b2","v2.2b1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107888.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
