From f1ed2a97d34561cfa543a4988c323d674f6bede2 Mon Sep 17 00:00:00 2001 From: Luca Coelho Date: Fri, 26 Jun 2020 12:49:40 +0300 Subject: [PATCH] UPSTREAM: nl80211: fix memory leak when parsing NL80211_ATTR_HE_BSS_COLOR If there is an error when parsing the NL80211_ATTR_HE_BSS_COLOR attribute, we return immediately without freeing param.acl. Fit it by using goto out instead of returning immediately.
