DescriptionIn the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: validate monitor transmit frame lengths rtw_cfg80211_monitor_if_xmit_entry() removes the radiotap header and then reads the 802.11 frame control field without checking that a base 802.11 header remains. The data path also pulls the calculated 802.11, QoS and SNAP header span before confirming that the skb contains it. A truncated frame can therefore cause out-of-bounds reads or leave insufficient data for the Ethernet address writes. Reject frames that do not contain the base 802.11 header and data frames that do not contain their complete calculated header span.
