US Patent 11860996 Security concepts for web frameworks

Embodiments described herein provide for virtual machine (VM) based exploit mitigation techniques that can be used to harden web content frameworks and JavaScript Engines. Some embodiments described herein are also generally applicable to other system frameworks, libraries, and program code that executes on a processor that is vulnerable to an attack using a security exploit. Program code that implements the techniques described herein can prevent the use of security exploit attacks to bypass security properties within the program code.
