What is CVE-2026-114038?

A security flaw has been identified in Device-Mapper-Multipath that allows local users to exploit an out-of-bounds read condition. By sending a specially formatted command to the multipath daemon, an attacker may expose sensitive daemon memory, potentially leading to data leakage. Additionally, this vulnerability could result in a crash of the daemon, thereby creating a Denial of Service (DoS) situation. The issue underscores the importance of securing access to critical system daemons.
