In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: prevent NULL pointer dereference in mt7925_sta_set_decap_offload() Add a NULL check for msta->vif before accessing its members to prevent a kernel panic in AP mode deployment. This also fix the issue reported in [1]. The crash occurs when this function is triggered before the station is fully initialized. The call trace shows a page fault at mt7925_sta_set_decap_offload() due to accessing resources when msta->vif is NULL. Fix this by adding an early return if msta->vif is NULL and also check wcid.sta is ready. This ensures we only proceed with decap offload configuration when the station's state is properly initialized.
