|---|---|---|---|---|---|---|---|---|
| CVE-2025-11561 | Hig | 0.57 | 8.8 | 0.01 | 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.… | ||
| CVE-2021-3621 | Hig | 0.57 | 8.8 | 0.03 | Dec 23, 2021 | A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root… | ||
| CVE-2012-3462 | Hig | 0.57 | 8.8 | 0.02 | 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-2026-14474 | Hig | 0.50 | 8.8 | 0.01 | Jul 7, 2026 | A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting… | ||
| CVE-2026-104048 | Med | 0.44 | 6.8 | — | Oct 6, 2026 | A flaw was found in SSSD. In trust-enabled identity management environments, SSSD evaluates Host-Based Access Control (HBAC) rules by stripping domain qualifiers and comparing only short usernames. An authenticated user in a trusted domain who shares the same username as an… | ||
| CVE-2026-92821 | Med | 0.44 | 6.8 | — | Oct 6, 2026 | A flaw was found in SSSD. When configured to evaluate password expiration warnings before restrictive access rules in LDAP (Lightweight Directory Access Protocol) environments, an expired-password warning terminates rule evaluation early and treats the access request as… | ||
| CVE-2026-87853 | Hig | 0.42 | 7.5 | 0.00 | Sep 9, 2026 | A flaw was found in SSSD's IdP authentication provider. The eval_access_token_buf() function compares the OIDC subject identifier using strncmp() with the authenticated user's identifier length, performing a prefix comparison instead of an exact match. An attacker whose IdP… | ||
| CVE-2026-104046 | Med | 0.40 | 6.2 | — | Oct 6, 2026 | A flaw was found in SSSD (System Security Services Daemon). When Identity Provider (IdP) authentication is enabled, pre-authentication requests retain state in memory without being cleared or timed out. A local attacker can repeatedly initiate authentication flows without… | ||
| CVE-2026-104044 | Med | 0.40 | 6.2 | — | Oct 6, 2026 | A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM… | ||
| CVE-2026-104038 | Med | 0.38 | 5.9 | — | Oct 6, 2026 | A flaw was found in sssd. A remote attacker can cause a denial of service (DoS) by submitting a certificate that lacks an expected Security Identifier (SID) extension. In deployments configured with SID-based certificate mapping rules, the service fails to verify the presence of… | ||
| CVE-2026-104036 | Med | 0.38 | 5.8 | — | Oct 6, 2026 | A flaw was found in SSSD's NFS idmap plugin. When retrieving cached user or group names, the plugin detects if an entry exceeds the destination buffer size but fails to abort before copying data. A local attacker can trigger this vulnerability by requesting identity lookups that… | ||
| CVE-2026-104043 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | A flaw was found in SSSD. A local attacker with access to the Name Service Switch (NSS) responder UNIX socket can trigger an integer underflow by sending a specially crafted request with an undersized packet header. This issue causes an out-of-bounds memory read during packet… | ||
| CVE-2026-104042 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | A flaw was found in sssd. A local attacker can cause a Denial of Service (DoS) by sending a crafted Pluggable Authentication Module (PAM) request containing a zero-length authentication token to the responder socket. Due to missing input validation, the service attempts to read… | ||
| CVE-2026-104041 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | 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… | ||
| CVE-2026-104037 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | A flaw was found in SSSD. A local attacker can exploit this issue by sending a specially crafted request with an invalid packet length to the autofs responder UNIX socket. This causes an integer underflow and an out-of-bounds memory read, which can crash the responder process… | ||
| CVE-2026-104035 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | A flaw was found in SSSD. An issue in the Kerberos Credential Manager (KCM) responder allows a local user to cause a Denial of Service (DoS) by maintaining a persistent connection and repeatedly storing and destroying credentials. Because the service fails to release cached… | ||
| CVE-2026-104032 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | A flaw was found in SSSD. An unprivileged local user can repeatedly request master automount map updates through the autofs responder due to missing authorization checks. This triggers global cache invalidation and forces repeated lookups to backend directory providers, leading… | ||
| CVE-2026-104031 | Med | 0.36 | 5.5 | — | Oct 6, 2026 | A flaw was found in SSSD. In configurations where the autofs responder service is enabled, memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this vulnerability by maintaining an open… | ||
| CVE-2026-90995 | Med | 0.36 | 5.5 | 0.00 | Sep 14, 2026 | A flaw was found in SSSD (System Security Services Daemon). A local attacker with privileges to connect to the PAM (Pluggable Authentication Modules) responder socket can send a specially crafted protocol request. If the `pam_app_services` configuration is enabled and the… | ||
| CVE-2026-68743 | Med | 0.36 | 5.5 | 0.00 | Aug 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,… |
