  "details": "In the Linux kernel, the following vulnerability has been resolved:  tty: clear cdev pointer after cdev_add() failure  tty_cdev_add() drops the cdev reference when cdev_add() fails, but leaves driver-\u003ecdevs[index] pointing to freed memory. tty_unregister_device() later passes that stale pointer to cdev_del(), causing a use-after-free.  Clear the slot after dropping the reference.",
