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.

CVE-2026-19617 [MEDIUM] CWE-770 A flaw was found in libdm.
A flaw was found in libdm. A remote 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.

CVE-2026-19617 [MEDIUM] CWE-770 libdm: lvm2: libdm: Denial of Service via uncontrolled recursion in config parser
libdm: lvm2: libdm: Denial of Service via uncontrolled recursion in config parser
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.
Statement: This Moderate impact flaw in libdm's configuration parser can lead to a denial of service. A local attacker with the ability to create or modify LVM metadata could craft a deeply nested configuration, causing LVM commands to crash due to uncontrolled recursion and stack exhaustion. This primarily affects systems

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.
The libdm configuration file parser in libdm-config.c uses recursive descent parsing with no depth limit. A crafted LVM metadata configuration with deeply nested structures causes uncontrolled recursion, exhausting the stack and crashing any LVM command that reads the metadata.
