Critical: Local Privilege Escalation Vulnerabilities Found in Linux
2025-06-23

Two newly discovered local privilege escalation (LPE) vulnerabilities allow attackers to gain root privileges on systems running major Linux distributions. The first flaw (CVE-2025-6018) resides in the PAM framework configuration on openSUSE Leap 15 and SUSE Linux Enterprise 15, granting local attackers 'allow_active' user privileges. The second (CVE-2025-6019), found in libblockdev, allows an 'allow_active' user to gain root via the udisks daemon. Qualys TRU has developed proof-of-concept exploits, successfully achieving root on Ubuntu, Debian, Fedora, and openSUSE Leap 15. Immediate patching is crucial.
