Intel CPUs have been known to contain hardware vulnerabilities for years now. However, a group of researchers from the Graz University of Technology have revealed that AMD CPUs have had them all along as well.
The white paper released by the researchers describes a vulnerability called “Take A Way” that is able to leak data off of AMD CPUs dating back to 2011. This means that whether it is an old Athlon 64 X2 or a new high-end Ryzen 7 processor, they’ve all been vulnerable to cyberattacks all along.
The flaw has already been pointed out to AMD and the chipmaker responded to it claiming that “these are not new speculation based attacks”.
We are aware of a new whitepaper that claims potential security exploits in AMD CPUs, whereby a malicious actor could manipulate a cache-related feature to potentially transmit user data in an unintended way. The researchers then pair this data path with known and mitigated software or speculative execution side channel vulnerabilities. AMD believes these are not new speculation-based attacks.
As always, the statement advises users to keep their systems up to date to stay safe from such vulnerabilities.
