CVE-2026-90111

CVE-2026-90111 is a slab use-after-free in the Linux kernel's IPv6 multicast routing (ip6mr) subsystem. When an ingress multicast packet misses the MFC lookup, the skb is queued on the unresolved queue, escaping the receive-side RCU grace period. If the underlying route is subsequently deleted an...
