CVE-2018-3665

Priority
Medium
Description
System software utilizing Lazy FP state restore technique on systems using
Intel Core-based microprocessors may potentially allow a local process to
infer data from another process through a speculative execution side
channel.
Ubuntu-Description
Julian Stecklina and Thomas Prescher discovered that FPU register states
(such as MMX, SSE, and AVX registers) which are lazily restored are
potentially vulnerable to a side channel attack. A local attacker could use
this to expose sensitive information.

Notes
 tyhicks> Xenial and Trusty are affected when running on older x86 processors
  that do not have support for the xsaveopt instruction. You can verify if your
  system has support for xsaveopt by locating the "xsaveopt" feature listed in
  the flags section of the /proc/cpuinfo file.
 tyhicks> Precise is affected on all x86 processors.
