Mitigation Strategies

Apply the patch or update the Linux kernel to a version where the rtw89 driver has fixed the potential memory leak by properly freeing allocated memory in rtw89_append_probe_req_ie().

Executive Summary

This vulnerability is a potential memory leak in the Linux kernel's wifi driver rtw89, specifically in the function rtw89_append_probe_req_ie(). The fix involves freeing allocated memory (kfree_skb(new)) before exiting the function to prevent the leak.

Impact Analysis

A memory leak in the wifi driver could lead to increased memory usage over time, potentially causing system instability or crashes if the leak is exploited or occurs frequently.
