# CVE-2025-21692-poc

This is code for my exploit of the [CVE-2025-21692](https://nvd.nist.gov/vuln/detail/CVE-2025-21692) ets qdisc vulnerability, which accompanies my [writeup](https://volticks.github.io/CVE-2025-21692-nday-writeup/).
*Bear in mind that as specified in the writeup the kernel version was patched to enable the vulnerability, 6.6.75 is not vulnerable without removing the patch, but on older, vulnerable kernels this can work*.

The initramfs used for testing can be found [here](https://github.com/hoefler02/CVE-2025-21756) (thanks hoefler). 
The kernel config used is present in this repo with the adjustments made. 
The kernel and initramfs used to test the final exploit was build with [like-dbg](https://github.com/0xricksanchez/like-dbg).

Hope this is useful :).
