Side-Channel Data Leakage in AMD Processors Affecting JavaScript Execution

CVE-2017-5926

What is CVE-2017-5926?

A security vulnerability in certain AMD processors allows for a side-channel attack through page table walks executed by the Memory Management Unit (MMU). This process unintentionally retains traces in the last level cache, which can be exploited to leak sensitive data and code pointers during JavaScript execution. This breach undermines Address Space Layout Randomization (ASLR), exposing systems to potential exploitation by malicious actors.
