Exploiting AMD Aldom648sys Arbitrary Pointer Dereference – Part 2

In the previous part, they discussed the basics of the vulnerability and how it can be triggered. In this part, they will explore the techniques that can be used to exploit the vulnerability and gain control of the vulnerable system.

One of the techniques that can be used to exploit this vulnerability is to create a specially crafted input that will cause the driver to dereference an arbitrary pointer. This can be done by creating a malicious input that contains a pointer to a location in memory that the attacker wants to control. When the driver processes this input, it will dereference the pointer, which will give the attacker control of the vulnerable system.

Another technique that can be used to exploit this vulnerability is to use a buffer overflow attack. This can be done by creating a malicious input that is larger than the buffer that the driver is expecting. When the driver processes this input, it will overflow the buffer and overwrite adjacent memory locations. This can be used to overwrite the return address of the function that is being called by the driver, which will allow the attacker to execute arbitrary code.

It is important to note that this vulnerability is only present in older versions of the Aldom648.sys driver. AMD has released a patch for this vulnerability, so it is important to make sure that your system is up to date with the latest patches.

In addition to the techniques discussed in this blog post, there are other techniques that can be used to exploit this vulnerability. It is important to be aware of these techniques and to take steps to protect your system from exploitation.

This concludes the second part of our series on the AMD Aldom648.sys arbitrary pointer dereference vulnerability. In the next part, they will discuss the techniques that can be used to mitigate this vulnerability.
