CVE-2026-89995

High

Description

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.
