Security :: New Flaw Enables Null Pointer Exploits?

I refrained from posting this in the Kernel Vulns thread earlier, due to its zero-day status. But now that the issue has been Slashdotted, there's no use in keeping us from publicly discussing this vulnerability. The link to the article (from which I quote below) is here. Brad Spengler's original announcement on the Dailydave mailing list is here.Quote:A researcher has published exploit code for a new vulnerability he discovered in the Linux kernel. The vulnerability is an especially interesting one in that the researcher who discovered it, Brad Spengler, has demonstrated that he can use the weakness to defeat many of the add-on security protections offered by SELinux and AppArmor.
