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.
