Description
It has been discovered that on some AMD CPUs, the RAS (Return Address Stack, also called RAP - Return Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology) is dynamically partitioned between non-idle threads. This allows an attacker to control speculative execution on the adjacent thread.
