-
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: fix several DMA buffer leaks
Nouveau manages GSP-RM DMA buffers with nvkmgspmem objects. Several of these buffers are never dealloced. Some of them can be deallocated right after GSP-RM is initialized, but the rest need to stay until the driver unloads.
Also futher bullet-proof these objects by poisoning the buffer and clearing the nvkmgspmem object when it is deallocated. Poisoning the buffer should trigger an error (or crash) from GSP-RM if it tries to access the buffer after we've deallocated it, because we were wrong about when it is safe to deallocate.
Finally, change the mem->size field to a sizet because that's the same type that dmaalloc_coherent expects.
