Today's hardware vulnerability: register file data sampling

Date:
Tue, 12 Mar 2024 20:38:49 +0000

Description:
The mainline kernel has just received a set of commits addressing the
"register file data sampling" hardware vulnerability. RFDS may allow a 
malicious actor to infer data values previously
	used in floating point registers, vector registers, or integer
	registers. RFDS does not provide the ability to choose which data
	is inferred Only Atom cores are affected, but those cores can be 
found inside a number
of processors.  See this documentation
commit for more information.
