| CVE-2026-104041 | 2 Redhat, Sssd | 3 Enterprise Linux, Openshift, Sssd | 2026-10-06 | 5.5 Medium |
| A flaw was found in SSSD. An unprivileged local user can repeatedly request lookups for nonexistent entries through the Name Service Switch (NSS) responder. Because the negative cache does not limit the total number of stored entries and only removes expired records when an existing key is rechecked, the cache can grow without bound. This behavior can lead to memory exhaustion, resulting in a Denial of Service (DoS) as the responder becomes unresponsive or terminates. | ||||
| CVE-2026-68744 | 3 Fedoraproject, Redhat, Sssd | 5 Sssd, Enterprise Linux, Openshift and 2 more | 2026-08-18 | 3.3 Low |
| A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose cached directory data and heap layout information from the sssd_nss process. | ||||
| CVE-2026-68742 | 3 Fedoraproject, Redhat, Sssd | 5 Sssd, Enterprise Linux, Openshift and 2 more | 2026-08-18 | 5.5 Medium |
| 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. | ||||
| CVE-2026-68743 | 3 Fedoraproject, Redhat, Sssd | 5 Sssd, Enterprise Linux, Openshift and 2 more | 2026-08-17 | 5.5 Medium |
| 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. | ||||
| CVE-2026-12610 | 3 Fedoraproject, Redhat, Sssd | 7 Sssd, Enterprise Linux, Hardened Images and 4 more | 2026-07-01 | 6.4 Medium |
| A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that disrupts authentication. This vulnerability also presents a potential for privilege escalation, although it is difficult to exploit. | ||||
