Scavenger - Misuse Error Handling Leading to Qemu - KVM Escape

Explore a critical security vulnerability in hypervisors through this 35-minute Black Hat conference talk. Delve into how incorrect implementation of error handling code and insufficient error propagation can lead to severe security issues, including privilege escalation. Learn about a full guest-to-host escape exploitation technique that leverages misused error handling in Qemu/KVM. Gain insights from security researchers Xingwei Lin, Gaoning Pan, Jiashui Wang, Chunming Wu, and Xinlei Ying as they demonstrate the potential risks associated with error handling code in virtualization environments.
