AMD Platform Security Processor (PSP) Chipset Driver Information Disclosure (AMD-SB-1009)

medium Nessus Plugin ID 153836

Language:

Synopsis

The remote host has a chipset driver that is affected by an information disclosure vulnerability.

Description

The version of the AMD Platform Security Processor (PSP) chipset driver found on the remote host is prior to 5.17.0.0.
It is, therefore, affected by an information disclosure vulnerability. The discretionary access control list (DACL) may allow low privileged users to open a handle and send requests to the driver resulting in a potential data leak from uninitialized physical pages.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to AMD PSP driver 5.17.0.0 through Windows Update or by updating to AMD Chipset Driver 3.08.17.735.
