CVE-2022-42281
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 · uneditedNVIDIA DGX A100 contains a vulnerability in SBIOS in the FsRecovery, which may allow a highly privileged local attacker to cause an out-of-bounds write, which may lead to code execution, denial of service, compromised integrity, and information disclosure.
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 confidenceNVIDIA DGX A100 contains an out-of-bounds write vulnerability in the SBIOS FsRecovery component, exploitable by a highly privileged local attacker, potentially leading to code execution, denial of service, integrity compromise, and information disclosure.

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.
-
Check SBIOS firmware version on DGX A100Access the BMC web interface and navigate to the Firmware/BIOS section to view the installed SBIOS version, or use IPMI command: ipmitool -I lanplus -H <bmc_ip> -U admin -P <password> raw 0x3c 0x01 to query SBIOS versionAffected if SBIOS firmware version is below 1.18
-
Confirm system model is DGX A100Check the system model via BMC system information page or command: ipmitool -I lanplus -H <bmc_ip> -U admin -P <password> chassis status to verify the system is an DGX A100Affected if System model is DGX A100 with vulnerable firmware
-
Verify FsRecovery component is enabledCheck SBIOS configuration settings in BMC under SBIOS settings to see if the FsRecovery feature is enabledAffected if FsRecovery feature is enabled on a vulnerable firmware version
System is affected if it is an NVIDIA DGX A100 with SBIOS firmware version below 1.18 and FsRecovery component is present/enabled

Apply the NVIDIA-provided SBIOS firmware update for the DGX A100. This is a firmware-level fix requiring careful deployment following NVIDIA's update procedures.
DGX A100 Firmware version 1.18
- Identify the current DGX A100 firmware version using NVIDIA's system management interface or by running the relevant firmware query command
- Download the DGX A100 firmware version 1.18 or later from NVIDIA's official support portal (nvidia.custhelp.com)
- Follow NVIDIA's documented firmware update procedure for DGX A100, which typically involves using the system BIOS/UEFI interface or NVIDIA's deployment tools
- After flashing the new firmware, verify the SBIOS version has been updated to 1.18 or later
- Reboot the system to ensure the new firmware is fully operational
