CVE-2026-64423
CVE-2026-64423 affects the Linux kernel IPv4 IGMP multicast handling. The root cause is that, when a device is destroyed, ip_mc_destroy_dev() decrements the multicast membership refcount but fails to unlink the membership from the device’s multicast hash table (mc_hash) before RCUs reclaim the ob...
