  "details": "In the Linux kernel, the following vulnerability has been resolved:  blk-cgroup: fix disk reference leak in blkcg_maybe_throttle_current()  Add the missing put_disk() on the error path in blkcg_maybe_throttle_current(). When blkcg lookup, blkg lookup, or blkg_tryget() fails, the function jumps to the out label which only calls rcu_read_unlock() but does not release the disk reference acquired by blkcg_schedule_throttle() via get_device(). Since current-\u003ethrottle_disk is already set to NULL before the lookup, blkcg_exit() cannot release this reference either, causing the disk to never be freed.  Restore the reference release that was present as blk_put_queue() in the original code but was inadvertently dropped during the conversion from request_queue to gendisk.",
