Title:
BUG: unable to handle kernel NULL pointer dereference (aa_label_merge)
Status in AppArmor Linux application security framework:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
I had a kernel problem with one of my high availability VMs. This was not the
first occurence of the problem, it seems to appear every now and then.
The VM froze because of the Kernel bug appended as a text file. I had to hard
reset it.
I am running Ubuntu 14.04.2 Kernel 3.16.0-34-generic with
libapache2-mod-apparmor 2.8.95~2430-0ubuntu5.1 and apache 2.4.7-1ubuntu4.4
(mpm_prefork).
Unfortunately I am unable to reproduce the bug at will. This is a serious
problem for high availability VMs.
Looking at the trace, I assume this is a bug in AppArmor.
