CVE-2025-37943

In certain cases, hardware might provide packets with a length greater than the maximum native Wi-Fi header length. This can lead to accessing and modifying fields in the header within the ath12kdprxhundecapnwifi function for DPRXDECAPTYPENATIVEWIFI decap type and potentially resulting in invalid data access and memory corruption.

Add a sanity check before processing the SKB to prevent invalid data access in the undecap native Wi-Fi function for the DPRXDECAPTYPENATIVE_WIFI decap type.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
