PoC Exploit Released for Linux-PAM Vulnerability Allowing Root Privilege Escalation

A high-severity vulnerability in the Pluggable Authentication Modules (PAM) framework was assigned the identifier CVE-2025-8941. This vulnerability stems from the heart of Linux operating systems, enabling attackers with local access to exploit symlink attacks and race conditions for full root privilege escalation.

According to Ameeba’s blog, the vulnerability resides in the pam_namespace module, which manages namespaces for user sessions. A mishandling of user-controlled paths allows crafty attackers to insert symbolic links that hijack directory creation processes.

By exploiting a race condition where timing aligns perfectly, the attacker tricks the system into building sensitive structures on the root filesystem. Real-world exploitation would require sophisticated scripting and precise synchronization, but success grants root-level control, enabling malware deployment or data exfiltration.
