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

dma-direct: return struct page from dma_direct_alloc_from_pool()

Commit 5b138c534fda ("dma-direct: factor out a dma_direct_alloc_from_pool

helper") changed dma_direct_alloc_from_pool() to return the CPU address

from dma_alloc_from_pool(). That fits dma_direct_alloc(), but

dma_direct_alloc_pages() also uses the helper and expects a struct page *.

Fix this by making dma_direct_alloc_from_pool() return the struct page *

again, and pass the CPU address back through an out-parameter for the

dma_direct_alloc() caller. (NVD)

Monitor Linux's web page for any future patch releases.
