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

arm64: hibernate: Fix level3 translation fault in swsusp_save()

On arm64 machines, swsusp_save() faults if it attempts to access MEMBLOCK_NOMAP memory ranges. This can be reproduced in QEMU using UEFI when booting with rodata=off debug_pagealloc=off and CONFIG_KFENCE=n:

The reason is swsusp_save() -> copy_data_pages() -> page_is_saveable() -> kernel_page_present() assuming that a page is always present when can_set_direct_map() is false (all of rodata_full, debug_pagealloc_enabled() and arm64_kfence_can_set_direct_map() false), irrespective of the MEMBLOCK_NOMAP ranges. Such MEMBLOCK_NOMAP regions should not be saved during hibernation.

This problem was introduced by changes to the pfn_valid() logic in commit a7d9f306ba70 ("arm64: drop pfn_valid_within() and simplify pfn_valid()").

Similar to other architectures, drop the !can_set_direct_map() check in kernel_page_present() so that page_is_savable() skips such pages.
