      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.
