CVE-2022-49603

Summary

CVE-2022-49603 is a recently identified vulnerability in the Linux kernel. This issue involves a data race in the sysctl_ip_fwd_update_priority function, where the value can be concurrently changed while being read. To mitigate this, the kernel developers have implemented the READ_ONCE() macro to ensure consistent reading of the sysctl_ip_fwd_update_priority variable. By doing so, the Linux kernel now prevents data corruption and potential security risks associated with this race condition. This update is recommended for all Linux users to ensure the stability and security of their systems.
