OESA-2026-4790: multipath-tools security update

Published Nov 11, 2026
·
Updated

This package provides the multipath tool and the multipathd daemon to manage dm-multipath devices. multipath can detect and set up multipath maps. multipathd sets up multipath maps automatically, monitors path devices for failure, removal, or addition, and applies the necessary changes to the multipath maps to ensure continuous availability of the map devices. Security Fix(es):

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. This issue can allow the user to expose unintended daemon memory, leading to information disclosure, or cause the daemon to crash, resulting in a Denial of Service (DoS).(CVE-2026-114038)
