Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: libertas: reject short monitor TX frames
In monitor mode, lbs_hard_start_xmit() casts skb->data to a
radiotap TX header, skips that header, and then copies the 802.11
destination address from offset 4 in the remaining frame. The
generic length check only rejects zero-length and oversized skbs, so
a short monitor frame can be read past the end of the skb data.
Require enough bytes for the radiotap TX header and the destination
address field before using the monitor-mode header layout.
