Description
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.
