In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't allow injecting frames wider than the chanctx
Frames injected on a monitor interface can carry a radiotap
field requesting a bandwidth, which mac80211 passes down to
the driver regardless of the the actual operational bandwidth.
If the bandwidth requested is too wide, that triggers a warning
in hwsim:
WARN_ON(hwsim_get_chanwidth(bw) > hwsim_get_chanwidth(confbw))
Drop such frames entirely instead since they cannot be sent.
