Linux Kernel RCU-Based Socket Lookup Vulnerability in MCTP

A vulnerability has been addressed in the Linux kernel's handling of socket lookups for the Management Component Transport Protocol (MCTP). The issue arose because the socket binding lookup process was not properly synchronized, allowing a socket to be removed during the lookup, which could lead to unexpected behavior or errors.

Impact

Exploitation of this vulnerability could cause issues during socket lookups, potentially leading to errors or instability in applications using MCTP.
