CVE-2022-49601

Summary

CVE-2022-49601 is a newly identified vulnerability affecting the Linux kernel. The issue lies in the tcp/dccp module where a data-race condition was found in the function sysctl_tcp_fwmark_accept. Concurrent reads and writes to this function can result in incorrect data being processed, leading to potential security vulnerabilities. To mitigate this issue, the Linux developers have implemented the READ_ONCE() macro to ensure that the function is only read once during execution. This update resolves the data-race condition and improves the overall security of the Linux kernel.
