Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt76x0: fix oob access in mt76x0_phy_get_target_power After 'commit ba45841ca5eb ("wifi: mt76: mt76x02: simplify struct mt76x02_rate_power")', mt76x02 relies on ht[0-7] rate_power data for vht mcs{0,7}, while it uses vth[0-1] rate_power for vht mcs {8,9}. Fix a possible out-of-bound access in mt76x0_phy_get_target_power routine.
