Subject: [PATCH wireless 0/2] wifi: mwifiex: firmware response validation fixes (WMM + sta_list)
Date: Sun, 1 Nov 2026 21:51:10 +0000 [thread overview]
Message-ID: <20261101215112.3199197-1-tristmd@gmail.com> (raw)
From: Tristan Madani <tristan@talencesecurity.com>
Two input validation fixes for the mwifiex driver:
1/2: The WMM status response handler uses the firmware-provided
queue_index to index a 4-entry array without bounds checking.
Values >= IEEE80211_NUM_ACS cause an out-of-bounds access.
2/2: The AP station list response handler iterates over sta_info
entries using firmware-provided sta_count without verifying
the response buffer is large enough.
