Linux Kernel cipso Sysctl Data-Race Vulnerability

A data-race vulnerability has been identified in the Linux kernel's cipso implementation, specifically related to sysctl variables. When these variables are read, they can be concurrently modified, leading to potential inconsistencies. To address this issue, the READ_ONCE() function needs to be added to the code to prevent such data-races.

Impact

Exploitation of this vulnerability could lead to data inconsistency issues, where sysctl variables are read while being concurrently modified, potentially causing unexpected behavior in the system.
