CVE-2017-15596 xsa235 xen: add-to-physmap error paths fail to release lock on ARM
When dealing with the grant map space of add-to-physmap operations,
ARM specific code recognizes a number of error conditions, but fails
to release a lock being held on the respective exit paths.
A malicious guest administrator can cause a denial of service.
Specifically, prevent use of a physical CPU for an indefinite period
of time.

## Abstract
Dataflow tracking with Dynamic Taint Analysis (DTA) is an important method in systems security with many applications, including exploit analysis, guided fuzzing, and side-channel information leak detection. However, DTA is fundamentally limited by the Boolean nature of taint labels, which provide no information about the significance of detected dataflows and lead to false positives/negatives on complex real world programs.
We introduce proximal gradient analysis (PGA), a novel, theoretically grounded approach that can track more accurate and fine-grained dataflow information.
PGA uses p
