Subject: [PATCH wireless v2 0/2] wifi: rtw89: fix IE length passed to cfg80211_find_ie()
Date: Wed, 7 Oct 2026 16:17:19 +0000 [thread overview]
Message-ID: <20261007161721.261452-1-tristmd@gmail.com> (raw)
From: Tristan Madani <tristan@talencesecurity.com>
Two callers of cfg80211_find_ie() in rtw89 pass skb->len as the IE
data length, but since ies points past the management frame header
and fixed fields, the correct length is skb->len minus the header
offset. This causes cfg80211_find_ie() to potentially read past the
IE data boundary.
Changes since v1:
- Straightened the cfg80211_find_ie() call in wow.c to a single line
- Removed unnecessary blank line in wow.c
Both per Ping-Ke Shih review feedback.
