Default New Lazy FP State Restore Vulnerability Affects All Intel Core CPUs

More trouble for Intel! This report comes from Bleeping Computer:

New Lazy FP State Restore Vulnerability Affects All Intel Core CPUs
Quote:
What a horrible year in security for Intel. First we had the Meltdown and Spectre vulnerabilities that never seem to go away. Now Intel has announced a new speculative execution side channel vulnerability involving "Lazy FP state restore" that could allow a malicious program to read data being used by other processes.

According to Intel this new vulnerability affects all Intel Intel*Core-based microprocessors and is a bug in the actual CPU, so it does not matter what operating system the user is running. It could be Windows, Linux, BSD, or any other operating running an an Intel Core-based CPU and using "Lazy FPU context switching".

An article from The Register:

Boffins offer to make speculative execution great again with Spectre-Meltdown CPU fix The Register
Quote:
Good thing too because Intel's planned chip changes may break Google's Retpoline

A group of computer science researchers has proposed a way to overcome the security risk posed by speculative execution, the data processing technique behind the Spectre and Meltdown vulnerabilities.
