Linux Kernel TCP Data-Race Vulnerability in sysctl_tcp_migrate_req

A data-race vulnerability has been identified in the Linux kernel's TCP implementation, specifically concerning the sysctl_tcp_migrate_req parameter. This vulnerability arises because sysctl_tcp_migrate_req can be modified concurrently while it is being read. To address this issue, the kernel has been updated to include a READ_ONCE() directive for readers of this parameter.

Impact

The vulnerability could lead to inconsistent or unexpected behavior when reading the sysctl_tcp_migrate_req parameter, potentially causing issues in TCP connection migration processes.
