Summary: CVE-2026-68743 affects SSSD. The PAM responder’s extract_authtok_v1() does not validate auth_token_length against the remaining buffer, allowing a local attacker to craft a protocol v1 request to the PAM responder socket that can trigger an out-of-bounds read and cause a process crash (d...

CVE-2026-68744

CVE-2026-68744 concerns the SSSD NSS responder. The function sss_nss_protocol_fill_initgr() pre-allocates reply space for all groups but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be sent to the client. This enables a local attacker to disclose cached ...
