A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host.","published":"2026-10-06T02:17:04.000Z","lastModified":"2026-10-08T03:16:33.000Z","status":"Undergoing Analysis","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-476"],"affected":[],"epss":{"score":0.0012,"percentile":0.01812,"date":"2026-10-27","history":[{"date":"2026-10-06","score":0.0012,"percentile":0.01637}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.12%).
