AI-suggested

Red Hat has released updated packages (e.g., device-mapper-1.02.217-1.hum1 and lvm2-2.03.43-1.hum1) that fix this vulnerability. Users should apply these updates promptly. Additionally, avoid importing LVM physical volumes from untrusted sources without inspecting the metadata. Ensure that only trusted administrators have write access to LVM metadata and underlying block devices, especially on shared or externally-attached storage. No other specific mitigations are indicated.

Description

A vulnerability in libdm's Logical Volume Manager (LVM) metadata parser allows a local attacker to craft deeply nested LVM metadata configurations that cause uncontrolled recursion, exhausting the stack and crashing LVM commands. This leads to a denial of service (DoS) on affected systems. The flaw affects systems where untrusted users can write or modify LVM metadata. Mitigation involves restricting write access to LVM metadata and inspecting imported LVM physical volumes from untrusted sources. Red Hat has released updated packages to address this issue.
