From 366fc5858720b749d52a32ec15c8420939092b2a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 15 Dec 2018 11:03:22 +0200 Subject: [PATCH] nl80211: fix memory leak if validate_pae_over_nl80211() fails [ Upstream commit d350a0f431189517b1af0dbbb605c273231a8966 ] If validate_pae_over_nl80211() were to fail in nl80211_crypto_settings(), we might leak the 'connkeys' allocation. Fix this.
