CVE-2026-72323
CVE-2026-72323 — Linux kernel igmp UAF vulnerability : A race between device teardown (inetdev_destroy) and IGMP query processing (igmp_rcv) can cause a Use-After-Free in the IGMP timer callback when the timer is re-armed. The in_device memory is freed via RCU after its refcount reaches 0, but ig...
CVE-2026-72323 ipv4: igmp: Fix potential UAF in igmp_gq_start_timer()
In the Linux kernel, the following vulnerability has been resolved: ipv4: igmp: Fix potential UAF in igmpgqstarttimer A race condition exists between device teardown inetdevdestroy and incoming IGMP query processing igmprcv, leading to a Use-After-Free in the IGMP timer callback. During device...

CVE-2026-72321
CVE-2026-72321 affects the Linux kernel’s IGMP timer handling (ipv4: igmp). The root cause is a memory leak when deleting or stopping timers in igmp_mod_timer() and igmp_stop_timer(): refcount_dec(&im->refcnt) can drop the group entry im to zero on an RC reader path, leaving the im object leak...

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-2026-10636 Use-after-free in Zephyr IPv4 IGMP send path (`igmp_send`)
In Zephyr's IPv4 IGMP implementation, igmpsend in subsys/net/ip/igmp.c read the network interface back out of the packet via netpktifacepkt after the packet had been handed to netsenddata. On the successful-send path the packet's last reference may already have been released by the L2 driver or b...
