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

    wifi: ath12k: Pass ab pointer directly to ath12k_dp_tx_get_encap_type()

    In ath12k_dp_tx_get_encap_type(), the arvif parameter is only used to
    retrieve the ab pointer. In vdev delete sequence the arvif->ar could
    become NULL and that would trigger kernel panic.
    Since the caller ath12k_dp_tx() already has a valid ab pointer, pass it
    directly to avoid panic and unnecessary dereferencing.

    PC points to “ath12k_dp_tx+0x228/0x988 [ath12k]”
    LR points to “ath12k_dp_tx+0xc8/0x988 [ath12k]”.
