Intel® Secure Key is a digital random number generator located on the CPU that provides software applications with high quality pseudorandom numbers and random seeds. Software applications access this capability through the RDRAND and RDSEED instructions.
On some client and Intel® Xeon® E3 and E processors, a domain bypass transient execution attack known as special register buffer data sampling (SRBDS) may potentially allow malicious code executing on any core of the CPU to infer the data values returned by RDRAND and RDSEED.
This patch is a response to SRBDS related vulnerabilities.
