Google has announced a new bug bounty program with significant rewards for vulnerabilities found in the Kernel-based Virtual Machine (KVM) hypervisor.

The goal of the new program, named kvmCTF, is to help find and address vulnerabilities in the KVM hypervisor.

The bug bounty program works like a CTF event, with participants being able to reserve time slots to access a guest VM hosted in a lab environment, and attempt to conduct a guest-to-host attack. 

Google is hoping the project will help in identifying virtual machine escapes, arbitrary code execution flaws, information disclosure issues, and denial-of-service (DoS) bugs.  

“The goal of the attack must be to exploit a zero day vulnerability in the KVM subsystem of the host kernel. If successful, the attacker will obtain a flag that proves their accomplishment in exploiting the vulnerability,” Google explained in a blog post.

The highest reward, $250,000, can be earned for a full VM escape. Participants can earn $100,000 for an arbitrary memory write exploit, and $50,000 for an arbitrary memory read or a relative memory write exploit. DoS attacks can earn up to $20,000 and relative memory read flaws up to $10,000.

KVM is widely used in both consumer and enterprise solutions, including by the Android and Google Cloud platforms, which is why the internet giant wants to enhance the hypervisor’s security.
