In the Linux kernel, the following vulnerability has been resolved:
mm/mm_init: fix uninitialized struct pages for ZONE_DEVICE
If DAX memory is hotplugged into an unoccupied subsection of an early section, section_activate() reuses the unoptimized boot memmap. However, compound_nr_pages() still assumes that vmemmap optimization is in effect and initializes only the reduced number of struct pages. As a result, the remaining tail struct pages are left uninitialized, which can later lead to unexpected behavior or crashes.
Fix this by treating early sections as unoptimized when calculating how many struct pages to initialize.
