CVE-2026-64129

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