This issue was patched in RHSA-2022:8453.

NVD Description

Note: Versions mentioned in the description apply only to the upstream device-mapper-multipath package and not the device-mapper-multipath package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, exploited alone or in conjunction with CVE-2022-41973. Local users that are able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This issue occurs because an attacker can repeat a keyword, which is mishandled when arithmetic ADD is used instead of bitwise OR. This could lead to local privilege escalation to root.
