libblockdev: fix CVE-2025-6019

Browse Source 
CVE-2025-6019:
A 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.
