In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: fix several DMA buffer leaks

Nouveau manages GSP-RM DMA buffers with nvkm_gsp_mem 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 nvkm_gsp_mem 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 size_t because that's the same

type that dma_alloc_coherent expects.
