  "details": "In the Linux kernel, the following vulnerability has been resolved:  nvme-apple: Destroy the admin queue on removal  The admin queue is allocated with blk_mq_alloc_queue() but never destroyed. nvme_free_ctrl() only drops the last reference and blk_mq_exit_queue() and blk_sync_queue() never run: the hctx is never moved to q-\u003eunused_hctx_list and the timeout timer and work stay armed on a queue that is about to be freed which will eventually oops inside blk_mq_timeout_work().  This can only be triggered when the controller fails to come up and is then immediately torn down again which is why no one ever ran into this before.  Let's just copy what the pcie driver does: unquiesce and destroy the admin queue before nvme_uninit_ctrl().  With this the following WARN followed by a panic no longer happens:    WARNING: block/blk-mq.c:4390 at blk_mq_release+0x194/0x238, CPU#4: kworker/u34:4/119   CPU: 4 UID: 0 PID: 119 Comm: kworker/u34:4 Not tainted 7.2.0-rc1-dirty #248 PREEMPT   Hardware name: Apple Mac mini (M1, 2020) (DT)   Workqueue: nvme-wq apple_nvme_remove_dead_ctrl_work   pstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)   pc : blk_mq_release+0x194/0x238   lr : blk_mq_release+0x58/0x238   sp : ffffc000833a3b50   x29: ffffc000833a3b50 x28: ffff80001d0450f8 x27: ffff800020c95200   x26: 0000000000000088 x25: 0000000000000000 x24: ffff800020f36805   x23: 0000000000000000 x22: ffffc00081a86878 x21: ffff800020be9c60   x20: 0000000000000000 x19: ffff800022501698 x18: 000000000000000a   x17: 7365757165722066 x16: 666f7265776f7020 x15: 0000000000000000   x14: 0000000000000028 x13: 0000000000004def x12: 0000000000000003   x11: 0000000000000000 x10: 0000000000000000 x9 : ffffc000805b4fc8   x8 : ffffc00081915820 x7 : ffffc00081c4f3c8 x6 : 0000000000000001   x5 : 0000000000000004 x4 : ffff800022498d80 x3 : ffffc000833a3b14   x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff800022501698   Call trace:    blk_mq_release+0x194/0x238 (P)    blk_put_queue+0x8c/0xf0    nvme_free_ctrl+0x4c/0x260    device_release+0x44/0x128    kobject_put+0xa0/0x120    put_device+0x1c/0x40    nvme_uninit_ctrl+0x48/0x60    apple_nvme_remove+0x54/0xb0    platform_remove+0x28/0x40    device_remove+0x54/0x98    device_release_driver_internal+    device_release_driver+0x20/0x38    apple_nvme_remove_dead_ctrl_wor    process_one_work+0x1f4/0x770    worker_thread+0x1b8/0x360    kthread+0x140/0x160    ret_from_fork+0x10/0x20   irq event stamp: 448   hardirqs last  enabled at (447):in_unlock_irqrestore+0x74/0x80   hardirqs last disabled at (448): [\u003cffffc000811cf5c0\u003e] el1_brk64+0x20/0x60   softirqs last  enabled at (0): [ess+0xb28/0x2698   softirqs last disabled at (0): [\u003c0000000000000000\u003e] 0x0   ---[ end trace 0000000000000000   Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000   Mem abort info:     ESR = 0x0000000096000005     EC = 0x25: DABT (current EL),     SET = 0, FnV = 0     EA = 0, S1PTW = 0     FSC = 0x05: level 1 translation fault   Data abort info:     ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000     CM = 0, WnR = 0, TnD = 0, TagA     GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0   [0000000000000000] user address   Internal error: Oops: 0000000096000005 [#1]  SMP   CPU: 7 UID: 0 PID: 54 Comm: kwor          7.2.0-rc1-dirty #248PREEMPT   Tainted: [W]=WARN   Hardware name: Apple Mac mini (M1, 2020) (DT)   Workqueue: kblockd blk_mq_timeou   pstate: 01400005 (nzcv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)   pc : percpu_ref_tryget_many.cons   lr : percpu_ref_tryget_many.constprop.0+0xc0/0x168   sp : ffffc000829cbce0   x29: ffffc000829cbce0 x28: ffff800020be9f48 x27: ffff800013e503c0   x26: 0000000000000108 x25: 000009c05   x23: 0000000000000000 x22: ffffc000819f5000 x21: ffff800020be9f48   x20: ffff8001deda4808 x19: ffff8000a   x17: 00000000580e1fac x16: ffffc00082bbbb7c x15: 0000000000000000   x14: 0000000000000028 x13: 000000001   x11: 0000000000000000 x10: 0000000000000000 x9 : ffffc000829cbc20   x8 :  ---truncated---",
