CVE-2017-15537

Priority
Medium
Description
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.
Ubuntu-Description
Dmitry Vyukov discovered that the Floating Point Unit (fpu) subsystem in
the Linux kernel did not properly handle attempts to set reserved bits in a
task's extended state (xstate) area. A local attacker could use this to
cause a denial of service (system crash).

Notes
 sbeattie> requires a processor with the "xsave" feature but without the
  "xsaves" feature (e.g. Sandy Bridge through Broadwell for Intel.
