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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
