Summary

This vulnerability arises from the behavior of the Memory Management Unit (MMU) during virtual to physical address translation, which can leave trace data in the last level cache of modern Intel processors. An attacker can exploit this information through a side-channel attack to leak sensitive data and code pointers from JavaScript, effectively circumventing Address Space Layout Randomization (ASLR) protections. This compromise showcases the potential of cache analysis techniques to undermine confidentiality and integrity within affected systems.
