[Bug 58087] New: [-next] nouveau corrupts kernel mm allocator
...MD64)
Status: NEW
Version: unspecified
Component: Driver/nouveau
Product: xorg
Created attachment 71269
--> https://bugs.freedesktop.org/attachment.cgi?id=71269&action=edit
kernel log showing BUG triggered by nouveau
If nouveau_vm_new() fails in nouveau_drm_open(), the cleanup triggered corrupts
the kernel slab allocator (in this case, SLUB).
Attached is the kernel log showing the page allocation failure and the
subsequent BUG in mm/slub.c
A similar corruption had previously occurred which triggered a GP fault in the
mm allocator from the same code path....
