You can't run valgrind on the kernel (not because of the speed, but because the way valgrind works it's not technically feasible), but even if you could, the bad access only occurred when the particular type of packet was received. The kernel panic essentially was the kernel's run-time bad access detection triggering.

you can run the kernel in userspace so that valgrind can attach to it.

  It was done for UML kernel 2.6 with patches: http://web.archive.org/web/20100126181646/http://uml.jfdi.org/uml/Wiki.jsp?page=ValgrindingUML http://web.archive.org/web/20100126181646/http://uml.jfdi.or... . But today, it's impossible: http://marc.info/?l=user-mode-linux-user&m=140187124116532&w=2 http://marc.info/?l=user-mode-linux-user&m=140187124116532&w... > > So, is it possible to run linux (>3.12) with valgrind? If yes, how to do it? > No. > A long time ago it was possible after applying a patch to both UML and valgrind.

  But why would you want to? There's kasan, which is faster and catches more bug classes.
