QEMU NBD Server Vulnerability: DoS Attack via Socket Closure

CVE-2024-7409

What is CVE-2024-7409?

A flaw in the QEMU NBD Server allows attackers to initiate a Denial of Service (DoS) by exploiting improper synchronization during the closure of sockets. When a client maintains an open socket while the server goes offline, this vulnerability can be triggered, causing disruptions to service availability and potentially leading to resource exhaustion. This underscores the importance of proper synchronization mechanisms in server-client communications to mitigate such risks.
