high Tenable Cloud Security Plugin ID 475296

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-89995)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
