Hi,

notifications from AlmaLinux.

AlmaLinux: 8
Type: Security
Severity: Important
Release date: 2025-06-20

Summary:

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):

* libblockdev: 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. (CVE-2025-6019)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments,
