Hi,

The following vulnerability was published for multipath-tools.

CVE-2026-89329[0]:
| 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.
