Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From VID-D2C2C815-3793-11EA-8BE3-54E1AD3D6335:

Intel reports:

.A potential security vulnerability in Intel(R) Processor Graphics

may allow information disclosure. Intel is releasing software

updates to mitigate this potential vulnerability.

Description: Insufficient control flow in certain data

structures for some Intel(R) Processors with Intel(R) Processor

Graphics may allow an unauthenticated user to potentially enable

information disclosure via local access.

This patch provides mitigation for Gen9 hardware only. Patches

for Gen7 and Gen7.5 will be provided later. Note that Gen8 is not

impacted due to a previously implemented workaround. The mitigation

involves using an existing hardware feature to forcibly clear down

all EU state at each context switch.
