CVE-2025-6019 Detail
Awaiting Analysis
This CVE record has been marked for NVD enrichment efforts. DescriptionA Local Privilege Escalation (LPE) vulnerability was found in libblockdev. Generally, the "allow_active" setting in Polkit permits a physically present user to take certain actions based on the session type. Due to the way libblockdev interacts with the udisks daemon, an "allow_active" user on a system may be able escalate to full root privileges on the target host. Normally, udisks mounts user-provided filesystem images with security flags like nosuid and nodev to prevent privilege escalation. However, a local attacker can create a specially crafted XFS image containing a SUID-root shell, then trick udisks into resizing it. This mounts their malicious filesystem with root privileges, allowing them to execute their SUID-root shell and gain complete control of the system. Metrics
