MSI has updated BIOS versions for their Intel 100, 200, and 300 series motherboards. They’re the latest of several manufacturers, including Gigabyte a week ago, to address security vulnerabilities in Intel’s TXE (Trusted Execution Engine). Intel says they have “provided system and motherboard manufacturers with the necessary firmware and software updates,” so it’s now up to those manufacturers to implement them. An Intel tool that detects whether systems are vulnerable is available here, as well as a list of vendors that have already released updates.

Owners of affected MSI motherboards should visit and find their model. BIOS and other downloads can be found under the “service” tab for each board. Instructions are similar for most other manufacturers.
