| CVE-2025-11561 | Hig | 0.57 | 8.8 | 0.00 | Oct 9, 2025 | A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts. | |
| CVE-2026-6245 | Med | 0.36 | 5.5 | 0.00 | Apr 15, 2026 | A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data is treated as a NUL-terminated C string without explicit termination, it results in an out-of-bounds read when processed by functions like snprintf(). A local attacker could potentially trigger this vulnerability by initiating a crafted passkey authentication request, causing the SSSD PAM responder to crash, resulting in a local Denial of Service (DoS). | |
| CVE-2012-3462 | 0.00 | — | 0.00 | Dec 26, 2019 | A flaw was found in SSSD version 1.9.0. The SSSD's access-provider logic causes the result of the HBAC rule processing to be ignored in the event that the access-provider is also handling the setup of the user's SELinux user context. | ||
| CVE-2017-12173 | 0.00 | — | 0.00 | Jul 27, 2018 | It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it. |
