New Compat Vulnerabilities in Linux Device Drivers

Explore the security implications of compat system calls in 64-bit Linux kernels through this 24-minute Black Hat conference talk. Delve into how these calls enable 32-bit process compatibility and the potential vulnerabilities arising from implementing separate compat and non-compat interfaces. Learn about newly discovered compat vulnerabilities in Linux device drivers, presented by researchers Pengfei Ding and Chenfu Bao.
