Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: fix list corruption after hardware restart Since stations are recreated from scratch, all lists that wcids are added to must be cleared before calling ieee80211_restart_hw. Set wcid->sta = 0 for each wcid entry in order to ensure that they are not added again before they are ready.

Executive Summary

This vulnerability is related to the Linux kernel's wifi driver for the mt7915 device. It involves list corruption that occurs after a hardware restart. Specifically, when stations are recreated from scratch during a restart, the lists that contain wcids (wireless client IDs) must be cleared properly. The fix involves setting the wcid->sta to 0 for each wcid entry to ensure they are not added again before they are ready, preventing list corruption.

Impact Analysis

The vulnerability can cause list corruption in the wifi driver after a hardware restart, which may lead to instability or malfunction of the wireless networking functionality on affected devices using the mt7915 driver in the Linux kernel.
