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

A high-severity local privilege escalation vulnerability (CVE-2025-8941, CVSS 7.8) was disclosed in the Linux-PAM pam_namespace module; attackers with local, low-privileged access can exploit symlink and race-condition issues to escalate to root. The report covers affected distributions (e.g., Ubuntu, Fedora, RHEL), describes exploitation mechanics and a pseudocode example, and recommends immediate patching, disabling pam_namespace if unnecessary, and monitoring for suspicious symlink activity.
