In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: mac80211_hwsim: don’t hand frames to mac80211 while stopping<\/p>\n
The code checks ->started for frames coming from wmediumd, but the
\nradio can be stopped after the check and before frame delivery,
\ncausing mac80211 to hit the WARN_ON(!local->started).<\/p>\n
Expand the mutex for this case and synchronise against it when the
\nradio is stopped to avoid being able to hit the warning with hwsim.<\/p>\n
Drop the error print that would’ve complicated the error path, it
\nonly triggers for allocation failures (already noisy) and malformed
\nframes anyway.<\/p>\n","protected":false},"excerpt":{"rendered":"
