1) Reliance on undefined behavior

EUVDB-ID: #VU84028

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-20592

CWE-ID: CWE-758 - Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to unexpected behavior of the INVD instruction in some AMD CPUs. A malicious hypervisor can affect cache line write-back behavior of the CPU and modify guest virtual machine (VM) memory.

Mitigation

Install update from vendor's website.
