Linux Kernel TCP Data-Race Vulnerability in sysctl_tcp_thin_linear_timeouts

A data-race vulnerability has been identified in the Linux kernel's TCP implementation, specifically regarding the sysctl_tcp_thin_linear_timeouts parameter. While this parameter is being read, it can be concurrently modified, leading to potential inconsistencies. The vulnerability has been addressed by adding a READ_ONCE() directive to the reader.

Impact

Exploitation of this vulnerability could lead to a data race condition, causing inconsistent behavior when accessing the sysctl_tcp_thin_linear_timeouts parameter.
