FreeBSD : drm graphics drivers -- potential information disclusure via local access (d2c2c815-3793-11ea-8be3-54e1ad3d6335)

medium Nessus Plugin ID 132943

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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.

Solution

Update the affected packages.
