Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.10.0-64.eln141.aarch64

Description The issue is related to page table locking for hugetlb folios that are not mapped using a single PMD/PUD. GUP's common page table walking code will perform a pte offset map lock() to grab the PTE table lock, but hugetlb that concurrently modifies these page tables would actually grab the mm->page table lock, resulting in differing locks when USE SPLIT PTE PTLOCKS is used. This can be reproduced by triggering a warning at mm/gup.c:142 try grab folio+0x11c/0x188.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
