nvme: fix admin request_queue lifetime
In the Linux kernel, the following vulnerability has been resolved: nvme: fix admin request_queue lifetime The namespaces can access the controller's admin request_queue, and stale references on the namespaces may exist after tearing down the controller. Ensure the admin request_queue is active by moving the controller's 'put' to after all controller references have been released to ensure no one is can access the request_queue. This fixes a reported use-after-free bug: BUG: KASAN: slab-use-after-free in blk_queue_enter+0x41c/0x4a0 Read of size 8 at addr ffff88c0a53819f8 by task nvme/3287 CPU: 67 UID: 0 PID: 3287 Comm: nvme Tainted: G E 6.13.2-ga1582f1a031e #15 Tainted: [E]=UNSIGNED_MODULE Hardware name: Jabil /EGS 2S MB1, BIOS 1.00 06/18/2025 Call Trace: dump_stack_lvl+0x4f/0x60 print_report+0xc4/0x620 ? _raw_spin_lock_irqsave+0x70/0xb0 ? _raw_read_unlock_irqrestore+0x30/0x30 ? blk_queue_enter+0x41c/0x4a0 kasan_report+0xab/0xe0 ? blk_queue_enter+0x41c/0x4a0 blk_queue_enter+0x41c/0x4a0 ? __irq_work_queue_local+0x75/0x1d0 ? blk_queue_start_drain+0x70/0x70 ? irq_work_queue+0x18/0x20 ? vprintk_emit.part.0+0x1cc/0x350 ? wake_up_klogd_work_func+0x60/0x60 blk_mq_alloc_request+0x2b7/0x6b0 ? __blk_mq_alloc_requests+0x1060/0x1060 ? __switch_to+0x5b7/0x1060 nvme_submit_user_cmd+0xa9/0x330 nvme_user_cmd.isra.0+0x240/0x3f0 ? force_sigsegv+0xe0/0xe0 ? nvme_user_cmd64+0x400/0x400 ? vfs_fileattr_set+0x9b0/0x9b0 ? cgroup_update_frozen_flag+0x24/0x1c0 ? cgroup_leave_frozen+0x204/0x330 ? nvme_
