Spectre 10 _verified_ Link

The classic Spectre variant exploits conditional branches that check an array index (bounds check). The attacker trains the branch predictor to expect an in‑bounds index, then supplies an out‑of‑bounds index.

A or Prime+Probe attack measures access latency to a memory line. If a line is cached → fast access; if not cached → slow. This difference reveals which address was speculatively loaded. spectre 10

: Operating systems and software vendors have released patches that mitigate the effects of Spectre 10. These patches typically involve modifying the way software interacts with system registers to prevent speculative execution from revealing sensitive information. spectre 10
