Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU97948

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-20584

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient validation of special address ranges with invalid device table entries (DTEs) in IOMMU. A local user can induce DTE faults to bypass RMP checks in SEV-SNP.

Mitigation

Install updates from vendor's repository.
