- mm/migrate_device: fix spinlock leak in migrate_vma_insert_huge_pmd_page
- Details
-
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.
