In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
staging: rtl8723bs: validate monitor transmit frame lengths<\/p>\n
rtw_cfg80211_monitor_if_xmit_entry() removes the radiotap header and
\nthen reads the 802.11 frame control field without checking that a base
\n802.11 header remains.<\/p>\n
The data path also pulls the calculated 802.11, QoS and SNAP header
\nspan before confirming that the skb contains it. A truncated frame can
\ntherefore cause out-of-bounds reads or leave insufficient data for the
\nEthernet address writes.<\/p>\n
Reject frames that do not contain the base 802.11 header and data
\nframes that do not contain their complete calculated header span.<\/p>\n","protected":false},"excerpt":{"rendered":"
