a heap overflow vulnerability in the TIPC subsystem of the Linux kernel was disclosed by Max van Amerongen (@maxpl0it). He posted a detailed writeup about the bug on the SentinelLabs website.
It’s a pretty clear cut heap buffer overflow where we control the size and data of the overflow. I decided I wanted to embark on a small exploit dev adventure to see how hard it would be to exploit this bug on a kernel with common mitigations in place (SMEP/SMAP/KPTI).
The full exploit can be found here.
