DGX A100 SBIOS contains a vulnerability in the Pre-EFI Initialization (PEI)phase, where a privileged user can disable SPI flash protection, which may lead to denial of service, escalation of privileges, or data tampering.
The product uses a trusted lock bit for restricting access to registers, address regions, or other resources, but the product does not prevent the value of the lock bit from being modified after it has been set.
