CVE-2025-37943

wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifi

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifi

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 ath12k_dp_rx_h_undecap_nwifi function for
DP_RX_DECAP_TYPE_NATIVE_WIFI 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
DP_RX_DECAP_TYPE_NATIVE_WIFI decap type.
