In the Linux kernel, the following vulnerability has been resolved:
igmp: Fix data-races around sysctligmpllm_reports.
While reading sysctligmpllmreports, it can be changed concurrently. Thus, we need to add READONCE() to its readers.
This test can be packed into a helper, so such changes will be in the follow-up series after net is merged into net-next.
if (ipv4islocalmulticast(pmc->multiaddr) && !READONCE(net->ipv4.sysctligmpllm_reports))
