Beyond client work, our team contributes upstream. Here's how Hoverap's security research led to a fix that landed in an NVIDIA driver.
At Hoverap, security research doesn't stop at our clients' perimeters. While investigating the low-level components that our drone and monitoring platform depends on, our team identified — and helped fix — a bug in the NVIDIA [driver name] driver (version [xxx.xx]). This page tells the story of that contribution and why upstream engagement matters to us.
Modern security and AI workloads lean heavily on GPU acceleration. Our AI-assisted drone patrolling stack processes live video through NVIDIA GPUs, which means the reliability and security of the underlying graphics driver directly affects the trustworthiness of the whole system. During routine hardening and fuzzing of our video pipeline, we noticed anomalous behaviour originating from the kernel driver rather than our own code.
Deeper analysis traced the problem to [a memory-safety issue / an out-of-bounds access / an improper validation] in the driver's handling of [the affected ioctl / buffer / code path]. Under specific conditions, a local unprivileged process could [trigger a crash / read out-of-bounds memory / escalate privileges], impacting the availability and integrity of the host.
A simplified reproduction looked roughly like this:
// Placeholder — replace with the real (sanitized) reproduction snippet
int fd = open("/dev/nvidia0", O_RDWR);
struct nv_request req = { /* crafted parameters */ };
ioctl(fd, NV_ESC_[PLACEHOLDER], &req); // unexpected behaviour here
We confirmed the behaviour was reproducible across [affected versions] and prepared a minimal, responsibly-disclosed report.
Following coordinated disclosure practices, we reported our findings to NVIDIA's product security team on [date], including a proof-of-concept and a proposed remediation. After validation, the fix — [adding proper bounds checking / validating the input length before use] — was incorporated into a subsequent driver release.
Assigned identifier: [CVE-XXXX-XXXXX] · Fixed in NVIDIA driver [version].
Security is a shared responsibility. When we harden our own products, we frequently find issues that affect the wider ecosystem. Reporting them upstream — instead of keeping them to ourselves — makes the tools everyone relies on safer, and reflects the standard of trust we hold ourselves to at Hoverap.
