CVE-2026-114038 Device-mapper-multipath: device-mapper-multipath: information disclosure via malformed format string
Description
A flaw was found in device-mapper-multipath. A local user can trigger an out-of-bounds read by sending a command with a format string ending in a trailing percent character to the multipath daemon.
