CVE-2026-68743
PUBLISHED
CVSS 5.5 MEDIUM
Reported by redhat · Published August 4, 2026
A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
