A critical flaw in EDK II, the open-source UEFI firmware code that most PC and server makers build their BIOS on, lets an unauthenticated attacker on the network interfere with a machine while it is booting over the network, before…
A memory-corruption bug in TianoCore EDK II, the open-source codebase that underpins much of the UEFI firmware industry, became public on October 27, 2026. Ars Technica reported that the flaw, tracked as CVE-2026-97631, sits in an ICMP component and may allow code…
I'm working on oss-pce-cd-bios, an open-source effort to create a redistributable replacement for the PC Engine / TurboGrafx-CD System Card BIOS. In my October 22 update, the project had eight project-defined implementations connected to its 81 candidate entry points. As of October 29, the…
Defenders across the world face the burden of responding to yet another botched code-execution vulnerability, this time in boot-time firmware used by most of the world’s server vendors and data centers. As the official advisory puts it: Other recently discovered…
Anthropic and Google researchers had planned to disclose the UEFI firmware bug in January. A fix is now in the code, but servers stay exposed until firmware makers ship updates. A critical flaw in the firmware that starts most servers…
Rejoice, there is no reason to fear the fire hose of bad news drying up anytime soon. Your day can be ruined afresh, this time in the knowledge that every cloud provider… Yay! The Vast Majority Of Modern Servers Have…
Canonical is about to release its interim version of Ubuntu, the Stonking Stingray, a.k.a. Ubuntu 26.10, and they are doubling down on security with the upcoming Linux 7.3 kernel series, a slimmed-down GRUB bootloader, and more. Ubuntu 26.10 (codename Stonking Stingray) is scheduled for…
That led me to build EncryptedVhdBoot, an experimental x64 UEFI bridge. It authenticates the encrypted volume, decrypts the VHD reads needed before Windows starts, and passes VeraCrypt's standard boot state to veracrypt.sys. The bridge hooks VHD parser callbacks in two…
To be clear, it's only older motherboards for 8th and 9th Gen Intel CPUs that are affected by the issue. I'll be honest: BIOS updates give me the willies. Unfortunately, even as such a source of undue anxiety, they are still well…
