![]() Recovering the BIOS password from a Panasonic CF-U1 mk2 (AMI Aptio UEFI) I used UEFIToolNEA51win32.zip later versions should work fine. You can expand and collapse the various components of the image and dig deeper. The “Information” panel on the right side will show details of what is selected in the left panel: The new engine (NE) verson seems to deal with AMIs odd nvram format better. What you can do with UEFITool depends on the type of the image component you select. Below are screenshots illustrating the options available for each type of firmware component. Hopefully this will give you an idea of how the tool can help you. There is also a great search feature that lets you search your image for a hex pattern, GUID, or text.

The SMU version does not seem to relate to the AGESA PI version, because the version number stayed the same in de regression to Cezanne PI-FP6 1.0.0.1.UEFITool is free software released under the BSD License. I looked through all the BIOS settings screens, but no AGESA PI version was to be found there. I found the AGESA PI value in the UEFI module AmdVersionDxe. Unpatched Security vulnerabilities in v1.06 UEFI/BIOS image These patches still need to be propagated by OEM supplier Acer via a new UEFI/BIOS firmware update for their laptops. In AMD’s latest security bulletin AGESA PI release Cezanne PI-FP6 1.0.0.9a was published that patches them. The latest v1.06 UEFI/BIOS firmware release even digressed to AGESA PI version Cezanne PI-FP6 1.0.0.1. My hypothesis that the Acer Swift 3 SF314-43 laptop contains unpatched security vulnerabilities in the PSP is correct. They digressed back to version: Cezanne PI-FP6 1.0.0.1 How does the SMU version relate to the AGESA PI version?.Does anybody know if there would be a hidden option to make the AGESA PI version visible in the BIOS/UEFI Setup screens?.That probably is in the UEFI firmware setup program (the BIOS screens). I found the AGESA PI value in the UEFI module SetupUtility. Unpatched Security vulnerabilities in v1.04 UEFI/BIOS imageĭuring security reviews in collaboration with Google, Microsoft, and Oracle, potential vulnerabilities in the AMD Secure Processor (ASP), AMD System Management Unit (SMU), AMD Secure Encrypted Virtualization (SEV) and other platform components were discovered and have been mitigated in AMD AGESA™ PI packages.įor the AMD 5700U processor (an AMD Ryzen™ 5000 Series Mobile processor with Radeon™ graphics, internal name: “Lucienne”) the vulnerabilities are: These patches need to be propagated by OEM supplier Acer via a new UEFI/BIOS firmware update for their laptops. The latest v1.04 UEFI/BIOS firmware release contains AGESA PI version Cezanne PI-FP6 1.0.0.1a. PSP = Platform Security Processor (the PSP itself is a simple ARM Cortex processor core) AGESA PI version: Cezanne PI-FP6 1.0.0.9a ĪGESA = AMD’s Generic Encapsulated Software ArchitectureĪPU = AMD Accelerated Processing Unit, general purpose processors that feature integrated graphics processorsīIOS = Basic Input/Output Systen (is a legacy term that nowadays denotes UEFI firmware code).Platform: AMD Ryzen™ 5000 Series Mobile processor with Radeon™ graphics.In AMD’s may 2022 security bulletin (Bulletin ID: AMD-SB-1027) the latest AGESA PI update for the AMD Ryzen 5700U processor is listed as: ![]() Here is what the version string should look like: I also text searched in the V1.04 BIOS image, but couldn’t make sense of it. The BIOS settings neither contain an AGESA PI version string.
