The semiconductor manufacturer AMD is alerting users to a fresh set of flaws that might expose data and impact a wide variety of chipsets.
The defects, which are commonly referred to as Transient Scheduler Attacks (TSA), appear in its CPUs as a speculative side channel that takes advantage of the timing of instruction execution under particular microarchitectural circumstances.
According to AMD’s advice, under certain situations, an attacker would be able to utilize this timing information to extrapolate data from different contexts, which might lead to information leaking.
According to the company, problems were discovered during a study conducted by researchers from ETH Zurich and Microsoft that tested the isolation between security domains like virtual machines, kernels, and processes in order to test modern CPUs against speculative execution attacks like Meltdown and Foreshadow read more about AMD Warns of New Transient Scheduler Attacks Impacting a Wide Range of CPUs.
