UBUNTU-CVE-2026-89995: Medium severity ubuntu/linux-hwe-edge vulnerability

In the Linux kernel, the following vulnerability has been resolved: dma-direct: return struct page from dmadirectallocfrompool() Commit 5b138c534fda ("dma-direct: factor out a dmadirectallocfrompool helper") changed dmadirectallocfrompool() to return the CPU address from dmaallocfrompool(). That fits dmadirectalloc(), but dmadirectallocpages() also uses the helper and expects a struct page . Fix this by making dmadirectallocfrompool() return the struct page again, and pass the CPU address back through an out-parameter for the dmadirectalloc() caller.
