PACSafe: Leveraging ARM Pointer Authentication for Memory Safety in C/C++. (arXiv:2202.08669v1 [cs.CR])

Memory safety bugs remain in the top ranks of security vulnerabilities, even
after decades of research on their detection and prevention. Various
mitigations have been proposed for C/C++, ranging from language dialects to
instrumentation. Among these, compiler-based instrumentation is particularly
promising, not requiring manual code modifications and being able to achieve
precise memory safety. Unfortunately, existing compiler-based solutions
compromise in many areas, including performance but also usability and memory
safety guarantees. New developments in hardware can help improve performance
and …
