CVE-2022-49590
Description
In the Linux kernel, the following vulnerability has been resolved:
igmp: Fix data-races around sysctl_igmp_llm_reports.
While reading sysctl_igmp_llm_reports, it can be changed concurrently. Thus, we need to add READ_ONCE() 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 (ipv4_is_local_multicast(pmc->multiaddr) && !READ_ONCE(net->ipv4.sysctl_igmp_llm_reports))
