CVE-2026-64423

A flaw was found in the Linux kernel's Internet Group Management Protocol IGMP multicast group handling. When a network device is destroyed, its associated multicast groups are not properly removed from the device's hash table before their memory is reclaimed. This creates a race condition where ...

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...
