CVE-2026-43084

CVE-2026-43084 affects the Linux kernel netfilter nfnetlink_queue. The vulnerability stems from sharing a global hash table across all queues, allowing a parallel CPU to access a nf_queue_entry after it has been freed, causing a slab-use-after-free (KASAN) and potential crash/DoS. The fix is to m...
