x86: DoS from attempting to use INVPCID with a non-canonical addresses

ISSUE DESCRIPTION The INVPCID instruction raises GP0 if an attempt is made to invalidate a non-canonical address. Older flushing mechanisms such as INVLPG tolerate this without error, and perform no action. There is one guest accessible path in Xen where a non-canonical address was passed into th...

More Spectre/Meltdown-Like Attacks

Back in January, we learned about a class of vulnerabilities against microprocessors that leverages various performance and efficiency shortcuts for attack. I wrote that the first two attacks would be just the start: It shouldn't be surprising that microprocessor designers have been building...
