CVE-2026-74742

Linux kernel veth has a bug where veth_poll() derives the peer TX queue index from rq->xdp_rxq.queue_index, a field only populated when an XDP program is attached. On the plain GRO/NAPI path the value stays 0 for every queue. In a multi-queue setup with GRO enabled and no XDP, all NAPI pollers...

CVE-2026-74740

CVE-2026-74740 is a TOCTOU (time-of-check-time-of-use) NULL pointer dereference in the Linux kernel's net/sched: act_api subsystem. When handling TC_ACT_GOTO_CHAIN, tcf_action_exec() performs an initial rcu_access_pointer(a->goto_chain) check, then calls tcf_action_goto_chain_exec() which perf...

CVE-2026-74741

CVE-2026-74741 is a NULL pointer dereference in the Linux kernel's ngbe network driver, occurring in the non-MSI-X interrupt enabling path. When the driver operates in legacy INTx or single MSI mode, the wx->msix_entry pointer is not allocated or initialized, so calling NGBE_INTR_MISC(wx) dere...

CVE-2026-74739

CVE-2026-74739 is a slab-out-of-bounds read in the Linux kernel's net/sched cls_u32 traffic classification module. The root cause is in u32_bind_class(), which unconditionally casts a handle to tc_u_knode and dereferences &n->res; when the handle is actually a tc_u_hnode (hash table node with ...
