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...

CVE-2026-64408

The CVE concerns the Linux kernel Bluetooth BNEP path: during netdev registration, bnep_add_connection() reads the L2CAP connection without holding the channel lock, and passes the HCI device to register_netdev() while a controller teardown could clear the connection. The published fix is to take...
