Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU64364

Risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-21123

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to potentially sensitive information.

The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.

Mitigation

Update the affected package linux to the latest version.
