NVD Description

Note: Versions mentioned in the description apply only to the upstream lvm2-testsuite package and not the lvm2-testsuite package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in libdm. A local attacker could craft a malicious Logical Volume Manager (LVM) metadata configuration with deeply nested structures. This could lead to uncontrolled recursion in the libdm configuration file parser, exhausting the stack and causing any LVM command reading the metadata to crash. This vulnerability results in a Denial of Service (DoS) for affected systems.
