Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Input validation error

EUVDB-ID: #VU64377

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-21180

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation in Memory Mapped I/O (MMIO) for some 14nm Client/Xeon E3 Intel® Processors. A local user can pass specially crafted input and perform a denial of service (DoS) attack in certain virtualized environments.

Mitigation

Install updates from vendor's website.
