The vulnerability of the way predictor implementation in AMD CPUs’ L1D cache architecture allows a hacker to gain access to memory on the same CPU’s physical core.

The vulnerability of the way predictor’s implementation for first-level cache data on AMD CPUs’ L1D cache relates to the fact that accessing the same memory cell from a different virtual address may cause that cell to be evicted from the L1D cache. Exploiting this vulnerability could allow a remo...
