This is a note to let you know that I have just added a patch titled mac80211: fix potential use-after-free to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From d704a39f9ff9ea3b801217c0de86090e0c99304d Mon Sep 17 00:00:00 2001 From: Johannes Berg <johannes.berg@intel.com> Date: Tue, 4 Mar 2014 11:43:28 +0100 Subject: mac80211: fix potential use-after-free commit d2722f8b87fb172ff2f31d3a2816b31d58678d40 upstream. The bss struct might be freed in ieee80211_rx_bss_put(), so we shouldn't use it afterwards.
