Linux Kernel Data-Race Vulnerability in sysctl_ip_autobind_reuse

A data-race vulnerability has been identified in the Linux kernel's handling of the sysctl_ip_autobind_reuse parameter. This vulnerability arises because the parameter can be changed concurrently while it is being read, leading to potential inconsistencies. The issue has been addressed by adding a READ_ONCE() directive to the parameter's reader, ensuring that changes are properly synchronized.

Impact

Exploitation of this vulnerability could lead to a data race condition, causing inconsistent reads of the sysctl_ip_autobind_reuse parameter.
