"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.");
