Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
mm/migrate_device: fix pgtable leak in migrate_vma_insert_huge_pmd_page<br />
<br />
When migrate_vma_insert_huge_pmd_page() jumps to unlock_abort due<br />
to a PMD check failure, the pgtable allocated earlier via<br />
pte_alloc_one() is never freed, causing a memory leak.<br />
<br />
Added free_abort label to release the pgtable in error path.
