Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't use rate mask for offchannel TX either Like the commit ab9177d83c04 ("wifi: mac80211: don't use rate mask for scanning"), ignore incorrect settings to avoid no supported rate warning reported by syzbot. The syzbot did bisect and found cause is commit 9df66d5b9f45 ("cfg80211: fix default HE tx bitrate mask in 2G band"), which however corrects bitmask of HE MCS and recognizes correctly settings of empty legacy rate plus HE MCS rate instead of returning -EINVAL. As suggestions [1], follow the change of SCAN TX to consider this case of offchannel TX as well.

El syzbot dividió y encontró la causa en el commit 9df66d5b9f45 (\\\"cfg80211: corrige la máscara de velocidad de bits de transmisión HE predeterminada en la banda 2G\\\"), que sin embargo corrige la máscara de bits de HE MCS y reconoce correctamente las configuraciones de la velocidad heredada vacía más la velocidad de HE MCS en lugar de devolver -EINVAL. Como sugerencias [1], siga el cambio de SCAN TX para considerar también este caso de TX fuera de canal.
