CVE-2026-64424

CVE-2026-64424 is a use-after-free in the Linux kernel's netpoll subsystem on the shutdown path. When __netpoll_cleanup() runs, it schedules an RCU callback that calls kfree(npinfo), but the TX worker (queue_process) is only cancelled via cancel_delayed_work(), which does not guarantee the worker...

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...
