Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: mac80211: don&#39;t use rate mask for offchannel TX either<br />
<br />
Like the commit ab9177d83c04 ("wifi: mac80211: don&#39;t use rate mask for<br />
scanning"), ignore incorrect settings to avoid no supported rate warning<br />
reported by syzbot.<br />
<br />
The syzbot did bisect and found cause is commit 9df66d5b9f45 ("cfg80211:<br />
fix default HE tx bitrate mask in 2G band"), which however corrects<br />
bitmask of HE MCS and recognizes correctly settings of empty legacy rate<br />
plus HE MCS rate instead of returning -EINVAL.<br />
<br />
As suggestions [1], follow the change of SCAN TX to consider this case of<br />
offchannel TX as well.<br />
