Description

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.

Attack-Flow Graph

Executive Summary

This vulnerability is an out-of-bounds (OOB) access issue in the Linux kernel's mt76x0 wireless driver, specifically in the mt76x0_phy_get_target_power function. It occurs because the driver incorrectly accesses rate_power data arrays, leading to potential memory access beyond the intended bounds.

Impact Analysis

The out-of-bounds access could potentially lead to undefined behavior such as crashes or memory corruption in the wireless driver, which might be exploited to cause denial of service or other unintended effects on the system's stability.
