Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: add missing check for rx wcid entries Non-station wcid entries must not be passed to the rx functions. In case of the global wcid entry, it could even lead to corruption in the wcid array due to pointer being casted to struct mt7996_sta_link using container_of.

Executive Summary

This vulnerability in the Linux kernel's wifi mt76 mt7996 driver involves a missing check for rx wcid entries. Non-station wcid entries should not be passed to the rx functions. If the global wcid entry is passed, it can lead to corruption in the wcid array because a pointer is incorrectly cast to a struct mt7996_sta_link using container_of.

Impact Analysis

The vulnerability can cause corruption in the wcid array within the wifi driver, which may lead to instability or unexpected behavior in the wireless functionality of the affected Linux kernel. This could potentially result in crashes or degraded network performance.
