CVE-2022-49590 (GCVE-0-2022-49590)

Vulnerability from cvelistv5 – Published: 2025-02-26 02:23 – Updated: 2025-10-01 19:36
VLAI?
Summary
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))
Severity ?
4.7 (Medium)
