Executive Summary

This vulnerability is a memory leak in the Linux kernel's mt7996 WiFi driver. Specifically, the mt7996_mcu_exit routine did not always purge MCU skb queues if the mt7996_firmware_state failed, leading to a memory leak. The fix ensures that the MCU skb queues are always purged in the mt7996_mcu_exit routine regardless of firmware state failure.

Impact Analysis

The memory leak could lead to increased memory usage over time, potentially causing system instability or crashes if the leaked memory accumulates. This could affect the reliability of WiFi functionality on affected Linux systems using the mt7996 driver.
