{"id":"AZL-102729","summary":"CVE-2026-90229 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-apple: Destroy the admin queue on removal\n\nThe admin queue is allocated with blk_mq_alloc_queue() but never\ndestroyed. nvme_free_ctrl() only drops the last reference and\nblk_mq_exit_queue() and blk_sync_queue() never run: the hctx is never\nmoved to q-\u003eunused_hctx_list and the timeout timer and work stay armed on\na queue that is about to be freed which will eventually oops inside\nblk_mq_timeout_work().\n\nThis can only be triggered when the controller fails to come up and is\nthen immediately torn down again which is why no one ever ran into this\nbefore.\n\nLet's just copy what the pcie driver does: unquiesce and destroy the admin\nqueue before nvme_uninit_ctrl().\n\nWith this the following WARN followed by a panic no longer happens:\n\n  WARNING: block/blk-mq.c:4390 at blk_mq_release+0x194/0x238, CPU#4: kworker/u34:4/119\n  CPU: 4 UID: 0 PID: 119 Comm: kworker/u34:4 Not tainted 7.2.0-rc1-dirty #248 PREEMPT\n  Hardware name: Apple Mac mini (M1, 2020) (DT)\n  Workqueue: nvme-wq apple_nvme_remove_dead_ctrl_work\n  pstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)\n  pc : blk_mq_release+0x194/0x238\n  lr : blk_mq_release+0x58/0x238\n  sp : ffffc000833a3b50\n  x29: ffffc000833a3b50 x28: ffff80001d0450f8 x27: ffff800020c95200\n  x26: 0000000000000088 x25: 0000000000000000 x24: ffff800020f36805\n  x23: 0000000000000000 x22: ffffc00081a86878 x21: ffff800020be9c60\n  x20: 0000000000000000 x19: ffff800022501698 x18: 000000000000000a\n  x17: 7365757165722066 x16: 666f7265776f7020 x15: 0000000000000000\n  x14: 0000000000000028 x13: 0000000000004def x12: 0000000000000003\n  x11: 0000000000000000 x10: 0000000000000000 x9 : ffffc000805b4fc8\n  x8 : ffffc00081915820 x7 : ffffc00081c4f3c8 x6 : 0000000000000001\n  x5 : 0000000000000004 x4 : ffff800022498d80 x3 : ffffc000833a3b14\n  x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff800022501698\n  Call trace:\n   blk_mq_release+0x194/0x238 (P)\n   blk_put_queue+0x8c/0xf0\n   nvme_free_ctrl+0x4c/0x260\n   device_release+0x44/0x128\n   kobject_put+0xa0/0x120\n   put_device+0x1c/0x40\n   nvme_uninit_ctrl+0x48/0x60\n   apple_nvme_remove+0x54/0xb0\n   platform_remove+0x28/0x40\n   device_remove+0x54/0x98\n   device_release_driver_internal+\n   device_release_driver+0x20/0x38\n   apple_nvme_remove_dead_ctrl_wor\n   process_one_work+0x1f4/0x770\n   worker_thread+0x1b8/0x360\n   kthread+0x140/0x160\n   ret_from_fork+0x10/0x20\n  irq event stamp: 448\n  hardirqs last  enabled at (447):in_unlock_irqrestore+0x74/0x80\n  hardirqs last disabled at (448): [\u003cffffc000811cf5c0\u003e] el1_brk64+0x20/0x60\n  softirqs last  enabled at (0): [ess+0xb28/0x2698\n  softirqs last disabled at (0): [\u003c0000000000000000\u003e] 0x0\n  ---[ end trace 0000000000000000\n  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000\n  Mem abort info:\n    ESR = 0x0000000096000005\n    EC = 0x25: DABT (current EL),\n    SET = 0, FnV = 0\n    EA = 0, S1PTW = 0\n    FSC = 0x05: level 1 translation fault\n  Data abort info:\n    ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000\n    CM = 0, WnR = 0, TnD = 0, TagA\n    GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0\n  [0000000000000000] user address\n  Internal error: Oops: 0000000096000005 [#1]  SMP\n  CPU: 7 UID: 0 PID: 54 Comm: kwor          7.2.0-rc1-dirty #248PREEMPT\n  Tainted: [W]=WARN\n  Hardware name: Apple Mac mini (M1, 2020) (DT)\n  Workqueue: kblockd blk_mq_timeou\n  pstate: 01400005 (nzcv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)\n  pc : percpu_ref_tryget_many.cons\n  lr : percpu_ref_tryget_many.constprop.0+0xc0/0x168\n  sp : ffffc000829cbce0\n  x29: ffffc000829cbce0 x28: ffff800020be9f48 x27: ffff800013e503c0\n  x26: 0000000000000108 x25: 000009c05\n  x23: 0000000000000000 x22: ffffc000819f5000 x21: ffff800020be9f48\n  x20: ffff8001deda4808 x19: ffff8000a\n  x17: 00000000580e1fac x16: ffffc00082bbbb7c x15: 0000000000000000\n  x14: 0000000000000028 x13: 000000001\n  x11: 0000000000000000 x10: 0000000000000000 x9 : ffffc000829cbc20\n  x8 : \n---truncated---","modified":"2026-09-18T14:17:50.698814300Z","published":"2026-09-17T17:17:18Z","upstream":["CVE-2026-90229"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90229"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102729.json"}}],"schema_version":"1.9.0"}
