Anyone know how this relates to the Training Solo attack that was just disclosed? https://www.vusec.net/projects/training-solo/
Training Solo: - Enter the kernel (and switch privilege level) and “self train” to mispredict branches to a disclosure gadget, leak memory.
Branch predictor race conditions: - Enter the kernel while your trained branch predictor updates are still in flight, causing the updates to be associated with the wrong privilege level. Again, use this to redirect a branch in the kernel to a disclosure gadget, leak memory.
