Vulnerability Title
nvme: fix admin request_queue lifetime
Source: CVE Program / CVE List V5
Vulnerability Description
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: <TASK> 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_ioctl+0x7c/0x2c0 blkdev_ioctl+0x1a8/0x4d0 ? blkdev_common_ioctl+0x1930/0x1930 ? fdget+0x54/0x380 __x64_sys_ioctl+0x129/0x190 do_syscall_64+0x5b/0x160 entry_SYSCALL_64_after_hwframe+0x4b/0x53 RIP: 0033:0x7f765f703b0b Code: ff ff ff 85 c0 79 9b 49 c7 c4 ff ff ff ff 5b 5d 4c 89 e0 41 5c c3 66 0f 1f 84 00 00 00 00 00 f3 0f 1e fa b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d dd 52 0f 00 f7 d8 64 89 01 48 RSP: 002b:00007ffe2cefe808 EFLAGS: 00000202 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00007ffe2cefe860 RCX: 00007f765f703b0b RDX: 00007ffe2cefe860 RSI: 00000000c0484e41 RDI: 0000000000000003 RBP: 0000000000000000 R08: 0000000000000003 R09: 0000000000000000 R10: 00007f765f611d50 R11: 0000000000000202 R12: 0000000000000003 R13: 00000000c0484e41 R14: 0000000000000001 R15: 00007ffe2cefea60 </TASK>
