It's not just video games or emails that get hacked. Numerous reports proved that also hardware components can become a gateway for unwelcome guests, including GPUs, printers or even gaming mice. The latest such information was provided by AMD in an announcement about a serious security vulnerability in the company's CPUs. It was discovered by ZeroPeril, a company that researches and develops technologies related to computer security.
CVE-2021-26333 (as the issue was marked) affects the Platform Security Processor driver and enables unauthorized persons not only access to passwords stored on a computer but also sending own data packets to it (which, of course, makes people vulnerable to many types of malware attacks). The vulnerability is present in many AMD CPUs, including:
- AMD Ryzen 1000, 2000, 3000, 4000 and 5000 Series processors (including versions with integrated graphics);
- AMD Ryzen Laptop Processors 2000, 3000, 4000 and 5000 Series;
- AMD Ryzen Threadripper 1st, 2nd and 3rd generation processors.
Fortunately, we don't have to wait for this bug to be fixed. AMD in cooperation with ZeroPeril has already prepared a patch available through Windows Updates (as 220.127.116.11) or directly from the company's website (version 3.08.17.735). This is more than we received for the vulnerability called Transient Execution of Non-canonical Accesses (similar to Meltdown known from Intel CPUs) - AMD left the problem to developers.
