Subject: [PATCH 0/8] [backports] l2tp use-after-free fixes for 4.4 stable
Date: Thu, 2 Apr 2020 18:32:42 +0100 [thread overview]
Message-ID: <20200402173250.7858-1-will@kernel.org> (raw)
Hi Greg,
Syzbot has been complaining about KASAN splats due to use-after-free
issues in the l2tp code on 4.4 Android kernels (although I reproduced
with latest 4.4 stable on my laptop):
https://syzkaller.appspot.com/bug?id=de316389db0fa0cd7ced6e564601ea8e56625ebc
These have been fixed upstream, but for some reason didn't get picked up
for stable. This series applies to 4.4.y and I've sent patches for 4.9
separately.
Thanks,
Will
