A fix is available — apply it.

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 released on this error path.
