This could result in a buffer overread.\n\nAdd an upfront length check before dereferencing skb-\u003edata as a\nwmi_cmd_hdr. The check is placed before the trace_ath11k_wmi_event()\ncall to preserve the existing trace semantics (tracing the full raw\nWMI event including the header), unlike the analogous ath12k fix which\ncould use skb_pull_data() directly.\n\nCompile tested only.",
