CVE-2016-3044

Published: 1 December 2016

The Linux kernel component in IBM PowerKVM 2.1 before 2.1.1.3-65.10 and 3.1 before 3.1.0.2 allows guest OS users to cause a denial of service (host OS infinite loop and hang) via unspecified vectors.

I haven't determined if this CVE is specific to IBM's
PowerKVM Linux distribution or if this is an issue in the Linux
kernel.

it sounds possibly like this might be a PowerKVM "rebrand"
of CVE-2016-5412. One of the two commits to address that was
93d17397e4e2182fdaad503e2f9da46202c0f1c3, which fixed a similar
failure condition: a guest could trigger a host CPU to spin forever
with interrupts disabled.  Furthermore, the IBM xforce vulnerability
page notes that the issue was reported on July 22, 2016, which also
happens to be the exact date of the aforementioned git commit.
looks like this is actually
