  "description": "In the Linux kernel, the following vulnerability has been resolved:  mm/debug_vm_pgtable: fix BUG_ON with pud advanced test  Architectures like powerpc add debug checks to ensure we find only devmap PUD pte entries.  These debug checks are only done with CONFIG_DEBUG_VM.  This patch marks the ptes used for PUD advanced test devmap pte entries so that we don\u0027t hit on debug checks on architecture like ppc64 as below.
