A new class of side channel vulnerabilities impacting all modern Intel chips have been disclosed, which can use speculative execution to potentially leak sensitive data from a system’s CPU.
Intel said that the newest class of vulnerabilities, dubbed Microarchitectural Data Sampling (MDS), consist of four different attacks, which all ultimately depend on different ways of executing side channel attacks to siphon data from impacted systems.
“First identified by Intel’s internal researchers and partners, and independently reported to Intel by external researchers, MDS is a sub-class of previously disclosed speculative execution side channel vulnerabilities and is comprised of four related techniques,” Intel said in an advisory released Tuesday. “Under certain conditions, MDS provides a program the potential means to read data that program otherwise would not be able to see.”
