  - wifi: mt7601u: fix an integer underflow Fix an integer underflow that leads to a null pointer dereference     in 'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet could be manipulated, which could     trigger an integer underflow of 'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently     causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be bypassed, eventually leading to a     dereference of the pointer 'p', which is a null pointer. Ensure that 'dma_len' is greater than     'min_seg_len'. Found by a modified version of syzkaller.

    Fix an integer underflow that leads to a null pointer dereference in     'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet     could be manipulated, which could trigger an integer underflow of     'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently     causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be     bypassed, eventually leading to a dereference of the pointer 'p', which     is a null pointer.

    Ensure that 'dma_len' is greater than 'min_seg_len'.
