Researchers from the University of Texas, the University of Illinois Urbana-Champaign and the University of Washington have found a new vulnerability affecting all modern AMD and Intel CPUs.
Dubbed “Hertzbleed,” the new family of side-channel attacks takes its name from the ability to use frequency side channels to potentially extract cryptographic keys from remote servers.
“Hertzbleed takes advantage of our experiments showing that, under certain circumstances, the dynamic frequency scaling of modern x86 processors depends on the data being processed,” the researchers wrote.
