  Exploiting kmalloc Based Buffer Overflows
------------------------------------------------------------------------

SUMMARY

kmalloc - "Linux Kernel memory allocation routine, kmalloc() ensures
physical address contiguity". Qobaiashi has published a paper that
introduces a technique that would allow attackers to exploit kmalloc based
overflows in Linux kernel modules.

DETAILS

Qobaiashi focus on a mechanism to exploit the Linux kernel for local
privilege. He explains how Slab Allocation process works and finally how
to reliably exploit overflows to execute arbitrary code.
