libblockdev security update
安全等级: High
公告ID: KylinSec-SA-2025-2726
发布日期: 2025年7月4日
关联CVE: CVE-2025-6019
libblockdev is a C library supporting GObject introspection for manipulation of block devices. It has a plugin-based architecture where each technology (like LVM, Btrfs, MD RAID, Swap...) is implemented in a separate plugin, possibly with multiple implementations (e.g. using LVM CLI or the new LVM DBus API).
Security Fix(es):
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.(CVE-2025-6019)
