- Summary
- 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/migratedevice: fix spinlock leak in migratevmainserthugepmdpage
When checkstableaddressspace() fails after the PMD spinlock has been acquired via pmdlock(), the code jumps directly to the abort label, bypassing the spinunlock() call in unlockabort. 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.
