USN-3469-1: Linux kernel vulnerabilities
Anthony Perard discovered that the Xen virtual block driver did not properly initialize some data structures before passing them to user space. A local attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. CVE-2017-10911 Bo Zhang discovered tha...
Linux kernel x86/fpu (Floating Point Unit) subsystem information disclosure vulnerability
The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. x86/fpu Floating Point Unit subsystem is one of the 32-bit floating point unit subsystems. A security vulnerability exists in the x86/fpu Floating Point Unit subsystem in...
Design/Logic Flaw
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 rtsigreturn system call, allowing local users to read...

UBUNTU-CVE-2015-8555
Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors...
