Exploitability Analysis: Smash the Ref Bug Class

In April 2020, security researcher Gil Dabah published a paper on a set of vulnerabilities he had discovered within the Win32k subsystem of the Windows operating system. These vulnerabilities demonstrated instances of a new class of bugs, dubbed “Smash the Ref.” Dabah’s research included 13 test...
