{"id":"AZL-106893","summary":"CVE-2026-107886 affecting package cups 2.4.19-1","details":"OpenPrinting CUPS before 2.4.20 contains a double-free in printer-class management. When CUPS-Add-Modify-Class replaces an existing class member list, add_class() frees pclass-\u003eprinters 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.","modified":"2026-10-10T14:17:32.442131381Z","published":"2026-10-09T04:18:05Z","upstream":["CVE-2026-107886"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107886"}],"affected":[{"package":{"name":"cups","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/cups"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.4.19-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-106893.json"}}],"schema_version":"1.9.0"}
