Advisory Category: Hardware
Impact of vulnerability : Information Disclosure
Severity rating : LOW
Original release: 06/11/2019
Last revised: 06/11/2019
Summary:
A potential security vulnerability in some microprocessors may allow partial
information disclosure via local access.
Vulnerability Details:
CVEID: CVE-2019-0174
Description: Logic condition in specific microprocessors may allow an
authenticated user to potentially enable partial physical address information
disclosure via local access.
CVSS Base Score: 3.8 Low
CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N
Affected Products:
Microprocessors:
Intel Core X-series Processors, 4th Generation Intel Core i5 Processors,4th
Generation Intel Core i3 Processors, Intel Pentium Processor G Series, Intel
Pentium Processor 3000 Series, Intel Celeron Processor 2000 Series, Intel Xeon
Processor E7 v3 Family, Intel Xeon Processor E5 v3 Family, Intel Xeon Processor
E3 v3 Family.
Recommendations:
Partial physical address information potentially disclosed through exploitation
of this vulnerability does not contain user secrets, but could potentially be
utilized to enhance unrelated attack methods. For published exploits that Intel
is aware of, Intel recommends users follow existing best practices including:
The use of DRAM modules resistant to Rowhammer style attacks.
