FreeBSD cd(4) driver kernel memory overwrite local privilege escalation

This repository contains a single C source file, 'exploit.c', which implements a local privilege escalation exploit targeting UNIX-like systems (likely FreeBSD) with a vulnerable CD-ROM device driver. The exploit works by creating a large number of child processes, each manipulating user credentials, and then performing a series of IOCTL calls to the '/dev/cd0' device. The IOCTL is crafted to reference a specific kernel memory address, and the exploit attempts to escalate privileges by corrupting kernel memory structures. The exploit requires the user to be in the 'operator' group to access the device and assumes the presence of the '/dev/cd0' device. If successful, the exploit will grant root privileges to one of the child processes. The repository is a proof-of-concept and does not include weaponized or framework-based code. The only fingerprintable endpoints are the '/dev/cd0' device file and the '/memory' shared memory object used for process coordination.
