Published Oct 27, 2025 · Updated Oct 27, 2025

Ecosystem: Amazon Linux

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2025-11561: A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, SSSD does not enable the Kerberos local authentication plugin (sssd_krb5_localauth_plugin), allowing an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users. This can result in unauthorized access or privilege escalation on domain-joined Linux hosts.
