New Class of CPU Flaws Affects Almost Every Intel Processor Since 2011

Researchers have released info on a new class of flaws in Intel CPUs that affects every processor made since 2011.

"ZombieLoad attack affects a wide range of desktops, laptops, and cloud computers with Intel processor generations released from 2011 onwards. It can be used to read data that is recently accessed or accessed in parallel on the same processor core," wrote the Hacker News (

"Dubbed Microarchitectural Data Sampling (MDS) attacks, the newest class of vulnerabilities consist of four different flaws, which, unlike existing attacks that leak data stored in CPU caches, can leak arbitrary in-flight data from CPU-internal buffers, such as Line Fill Buffers, Load Ports, or Store Buffers," wrote the Hacker News.

Hackers can exploit these vulnerabilities to leak privileged information data from an area of the memory that hardware safeguards deem off-limit and then weaponize it.
