Summary
This technical article details two critical security vulnerabilities discovered in NVIDIA's Linux Open GPU Kernel Modules - specifically a kernel stack use-after-free bug and a race condition. The vulnerabilities can be exploited by an attacker controlling a local unprivileged process to achieve kernel read and write primitives, potentially leading to privilege escalation. The article provides technical analysis of the bugs, demonstrates exploitation techniques through proof-of-concept code, and discusses the security implications for systems using NVIDIA's open source GPU drivers.
