CVE-2026-68742
Sssd: sssd: nss responder out-of-bounds read via unchecked addrlen in gethostbyaddr
Description
A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
