This is a note to let you know that I have just added a patch titled kvm: x86: fix kvm_apic_has_events to check for NULL pointer to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt15. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 56f70be462d8711482f06e8bb5ae8bbf86d27310 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini <pbonzini@redhat.com> Date: Sat, 30 May 2015 14:31:24 +0200 Subject: kvm: x86: fix kvm_apic_has_events to check for NULL pointer commit ce40cd3fc7fa40a6119e5fe6c0f2bc0eb4541009 upstream. Malicious (or egregiously buggy) userspace can trigger it, but it should never happen in normal operation.
