NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift/ose-rhel-coreos-8 package and not the openshift/ose-rhel-coreos-8 package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in multipathd. A local attacker with access to the multipathd UNIX control socket can exploit this vulnerability by sending valid commands and then ceasing to read replies. This action can cause the multipathd listener thread to block, leading to a Denial of Service (DoS) where legitimate Inter-Process Communication (IPC) operations may hang or time out. This issue does not result in privilege escalation, arbitrary code execution, or impact data confidentiality or integrity.
