Red Hat libdm. A local attacker: denial of service
Medium5.5CVE-2026-19617 · Published Aug 14, 2026 · updated Sep 1, 2026
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.
