CVE-2022-23814
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedFailure to validate addresses provided by software to BIOS commands may result in a potential loss of integrity of guest memory in a confidential compute environment.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in BIOS/hypervisor interaction allows software to provide unvalidated addresses to BIOS commands, potentially corrupting guest memory integrity in confidential compute environments (such as AMD SEV or Intel SGX). The lack of proper address validation could permit an attacker to manipulate memory boundaries and compromise isolation between the host and confidential guest VMs.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify AMD Milan Sp3 system hardwareCheck system hardware specifications or use commands like 'dmidecode' or vendor tools to confirm the platform is AMD Milan (Sp3)Affected if System is not AMD Milan Sp3 hardware - this vulnerability is specific to this platform
-
Determine BIOS/firmware versionRead the current BIOS/system firmware version via vendor tools, IPMI, or 'dmidecode -s bios-version', then compare to 1.0.0.9Affected if Firmware version is less than 1.0.0.9
-
Verify confidential computing feature statusCheck if AMD SEV (Secure Encrypted Virtualization) or other confidential computing features are enabled in the system BIOS/UEFI settings or via hypervisor configurationAffected if Confidential computing features (SEV, SEV-ES, SEV-SNP) are enabled and the firmware is vulnerable
-
Confirm running confidential guest VMsList active virtual machines and check their configuration for SEV/SGX memory encryption settings using hypervisor tools (e.g., 'virsh list', 'xl list', or cloud provider metadata)Affected if Confidential guest VMs are currently running on affected firmware with memory encryption enabled
User is affected if running AMD Milan Sp3 firmware versions below 1.0.0.9 with AMD SEV or similar confidential computing features enabled for guest virtual machines.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.0.0.9
Apply vendor-provided firmware and hypervisor patches that implement proper address validation for BIOS commands in confidential computing contexts. Verify that confidential compute VMs are running on updated platform firmware.
Milanpi Sp3 Firmware version 1.0.0.9 or later
- Obtain the AMD Milanpi Sp3 Firmware update version 1.0.0.9 or later from AMD's official support website
- Verify the firmware integrity using checksums provided by AMD before applying
- Apply the firmware update through the platform's recommended update mechanism (typically via BIOS flash utility, AMD update tool, or BMC/IPMI interface)
- After updating, verify the firmware version reflects 1.0.0.9 or later
- Confirm the system boots properly and that confidential compute environment features are functioning as expected
