In the Linux kernel, the following vulnerability has been resolved:
mm/migrate device: fix pgtable leak in migrate vma insert huge pmd page
When migrate vma insert huge pmd page() jumps to unlock abort due
to a PMD check failure, the pgtable allocated earlier via
pte alloc one() is never freed, causing a memory leak.
Added free abort label to release the pgtable in error path.
