About this tag
Firmware security covers the protection and integrity of low-level code that initializes hardware and boots an operating system. Discussions on WindowsForum.com include Microsoft's Secure Boot certificate updates, which replace expiring 2011-era trust anchors across Windows 10, Windows 11, and Windows Server to prevent pre-boot security degradation. Other topics involve AI-assisted decompilation of legacy firmware, such as Mark Russinovich's Apple II demo, where large language models surface real bugs in 6502 machine code, highlighting implications for embedded systems and industrial controllers. Additional threads address specific vulnerabilities like CVE-2019-14204 in U-Boot's NFS handler and CVE-2021-28216 in UEFI FPDT pointer handling, as well as high-severity ICS advisories affecting serial device gateways. These examples illustrate the breadth of firmware security challenges from boot anchors to microcontroller bugs.
