When CUPS-Add-Modify-Class replaces an existing class member list, add_class() frees pclass->printers without clearing the pointer. If subsequent validation fails, the class retains the dangling pointer; CUPS-Delete-Class subsequently frees the same allocation in cupsdDeletePrinter(). A client authorized to modify and delete classes can cause scheduler-wide denial of service. The default policy requires @SYSTEM privileges.","state":0,"publishedAt":"2026-10-09T04:00:29.308+00:00","modifiedAt":"2026-10-09T18:05:33.937+00:00","affected":[{"ecosystem":"Vendor product","name":"CUPS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"CUPS\",\n                    \"repo\": \"https://github.com/OpenPrinting/cups\",\n                    \"vendor\": \"OpenPrinting\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"2.4.20\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.4.8\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","score":2.3,"severity":"LOW"}],"references":["https://github.com/OpenPrinting/cups/security/advisories/GHSA-pwg4-pv39-8c22"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107886","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107886","identifiers":["CVE-2026-107886"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
