What the advisory describes

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.

Source: EUVD (ENISA), in the words of the advisory.

An estate covering these products can be recorded in Patchlage. An advisory about them appears in the next morning's situation report.

Patchlage reports hits and suspected hits. About everything else this system says nothing — neither this page nor the situation report ever claims that an estate is safe.
