CVE-2026-89329

EUVD-2026-76186
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.
