From fb99c7d4d6d0fb4fe5a953e0c5f6c37a5b796b98 Mon Sep 17 00:00:00 2001 From: Ilan Peer Date: Sun, 11 Sep 2022 16:55:12 +0300 Subject: [PATCH] wifi: cfg80211/mac80211: Fix ML element common size validation The Multi-Link element can be fragmented, thus its size can exceed 254. Thus, modify ieee80211_mle_size_ok() to use 'size_t len' instead of 'u8 len'.
