The x86/fpu (Floating Point Unit) subsystem in the Linux kernel before 4.13.5, when a processor supports the xsave feature but not the xsaves feature, does not correctly handle attempts to set reserved bits in the xstate header via the ptrace() or rt_sigreturn() system call, allowing local users to read the FPU registers of other processes on the system, related to arch/x86/kernel/fpu/regset.c and arch/x86/kernel/fpu/signal.c.

It was discovered that the KVM subsystem in the Linux kernel did not
properly keep track of nested levels in guest page tables. A local attacker
in a guest VM could use this to cause a denial of service (host OS crash)
or possibly execute arbitrary code in the host OS. (CVE-2017-12188)

## Abstract
We introduce , a novel technique for automatically learning system
call filtering policies for containerized microservices applications. At
run-time, automatically learns which system calls a program should
be allowed to invoke, while rejecting attempts to call spurious system calls.
Further, addresses many of the shortcomings of state-of-the-art
static analysis-based techniques, such as the ability to generate tight filters
for programs written in interpreted languages such as PHP, Python, and
JavaScript. has a simple and rob
