AMD CPU L1D Cache Memory Disclosure

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...

AMD L1D Cache Predictors AES Key Extraction

The vulnerability of the way predictor implementation in AMD processors’ L1D cache involves collisions with the hash function used to calculate tags, which are used to locate a channel in the L1D cache. Exploiting this vulnerability can allow an attacker to recover encryption keys in vulnerable A...
