In the Linux kernel, the following vulnerability has been resolved: mm/migrate_device: fix spinlock leak in migrate_vma_insert_huge_pmd_page When check_stable_address_space() fails after the PMD spinlock has been acquired via pmd_lock(), the code jumps directly to the abort label, bypassing the spin_unlock() call in unlock_abort. This causes the PMD spinlock to be permanently held, leading to a deadlock. Change the goto target from abort to unlock_abort to ensure the spinlock is always releas
