SLAM: Spectre based on Linear Address Masking

This repository contains the code and data of the S&P'24 paper titled

Leaky Address Masking: Exploiting Unmasked Spectre Gadgets with Noncanonical Address Translation.

For more information about the SLAM attack project, read the paper or visit this webpage about SLAM.

Overview

The contents of this repository are organized as follows:

• gadget: unmasked gadget scanner and results
• kernel: auxiliary kernel functionality
• mitigate/fineibt FineIBT mitigation
• mitigate/switch LAM/UAI-switching mitigation
• slam/amd/covert SLAM covert channel on AMD
• slam/intel/covert SLAM covert channel on Intel
• slam/intel/exploit SLAM end-to-end exploit on Intel
