Detailsinfo

A vulnerability, which was classified as critical, was found in device-mapper-multipath (version unknown). This affects an unknown function.

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.

This vulnerability is uniquely identified as CVE-2026-89329. The exploitability is told to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
