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.

MEDIUM 5.1EPSS 0.12%

Does this matter?

Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.

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. 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).
