Title

nfc: nci: add flush_workqueue to prevent uaf

Summary

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: add flush_workqueue to prevent uaf Our detector found a concurrent use-after-free bug when detaching an NCI device. The main reason for this bug is the unexpected scheduling between the used delayed mechanism (timer and workqueue). The race can be demonstrated below: Thread-1 Thread-2 | nci_dev_up() | nci_open_device() | __nci_request(nci_reset_req) | nci_send_cmd | queue_work(cmd_work) nci_unregister_device() | nci_close_device() | ... del_timer_sync(cmd_timer)[1] | ... | Worker nci_free_device() | nci_cmd_work() kfree(ndev)[3] | mod_timer(cmd_timer)[2] In short, the cleanup routine thought that the cmd_timer has already been detached by [1] but the mod_timer can re-attach the timer [2], even it is already released [3], resulting in UAF. This UAF is easy to trigger, crash trace by POC is like below [ 66.703713] ================================================================== [ 66.703974] BUG: KASAN: use-after-free in enqueue_timer+0x448/0x490 [ 66.703974] Write of size 8 at addr ffff888009fb7058 by task kworker/u4:1/33 [ 66.703974] [ 66.703974] CPU: 1 PID: 33 Comm: kworker/u4:1 Not tainted 5.18.0-rc2 #5 [ 66.703974] Workqueue: nfc2_nci_cmd_wq nci_cmd_work [ 66.703974] Call Trace: [ 66.703974] <TASK> [ 66.703974] dump_stack_lvl+0x57/0x7d [ 66.703974] print_report.cold+0x5e/0x5db [ 66.703974] ? enqueue_timer+0x448/0x490 [ 66.703974] kasan_report+0xbe/0x1c0 [ 66.703974] ? enqueue_timer+0x448/0x490 [ 66.703974] enqueue_timer+0x448/0x490 [ 66.703974] __mod_timer+0x5e6/0xb80 [ 66.703974] ? mark_held_locks+0x9e/0xe0 [ 66.703974] ? try_to_del_timer_sync+0xf0/0xf0 [ 66.703974] ? lockdep_hardirqs_on_prepare+0x17b/0x410 [ 66.703974] ? queue_work_on+0x61/0x80 [ 66.703974] ? lockdep_hardirqs_on+0xbf/0x130 [ 66.703974] process_one_work+0x8bb/0x1510 [ 66.703974] ? lockdep_hardirqs_on_prepare+0x410/0x410 [ 66.703974] ? pwq_dec_nr_in_flight+0x230/0x230 [ 66.703974] ? rwlock_bug.part.0+0x90/0x90 [ 66.703974] ? _raw_spin_lock_irq+0x41/0x50 [ 66.703974] worker_thread+0x575/0x1190 [ 66.703974] ? process_one_work+0x1510/0x1510 [ 66.703974] kthread+0x2a0/0x340 [ 66.703974] ? kthread_complete_and_exit+0x20/0x20 [ 66.703974] ret_from_fork+0x22/0x30 [ 66.703974] </TASK> [ 66.703974] [ 66.703974] Allocated by task 267: [ 66.703974] kasan_save_stack+0x1e/0x40 [ 66.703974] __kasan_kmalloc+0x81/0xa0 [ 66.703974] nci_allocate_device+0xd3/0x390 [ 66.703974] nfcmrvl_nci_register_dev+0x183/0x2c0 [ 66.703974] nfcmrvl_nci_uart_open+0xf2/0x1dd [ 66.703974] nci_uart_tty_ioctl+0x2c3/0x4a0 [ 66.703974] tty_ioctl+0x764/0x1310 [ 66.703974] __x64_sys_ioctl+0x122/0x190 [ 66.703974] do_syscall_64+0x3b/0x90 [ 66.703974] entry_SYSCALL_64_after_hwframe+0x44/0xae [ 66.703974] [ 66.703974] Freed by task 406: [ 66.703974] kasan_save_stack+0x1e/0x40 [ 66.703974] kasan_set_track+0x21/0x30 [ 66.703974] kasan_set_free_info+0x20/0x30 [ 66.703974] __kasan_slab_free+0x108/0x170 [ 66.703974] kfree+0xb0/0x330 [ 66.703974] nfcmrvl_nci_unregister_dev+0x90/0xd0 [ 66.703974] nci_uart_tty_close+0xdf/0x180 [ 66.703974] tty_ldisc_kill+0x73/0x110 [ 66.703974] tty_ldisc_hangup+0x281/0x5b0 [ 66.703974] __tty_hangup.part.0+0x431/0x890 [ 66.703974] tty_release+0x3a8/0xc80 [ 66.703974] __fput+0x1f0/0x8c0 [ 66.703974] task_work_run+0xc9/0x170 [ 66.703974] exit_to_user_mode_prepare+0x194/0x1a0 [ 66.703974] syscall_exit_to_user_mode+0x19/0x50 [ 66.703974] do_syscall_64+0x48/0x90 [ 66.703974] entry_SYSCALL_64_after_hwframe+0x44/0x ---truncated---

The main reason for this bug is the unexpected scheduling\nbetween the used delayed mechanism (timer and workqueue).\n\nThe race can be demonstrated below:\n\nThread-1                           Thread-2\n                                 | nci_dev_up()\n                                 |   nci_open_device()\n                                 |     __nci_request(nci_reset_req)\n                                 |       nci_send_cmd\n                                 |         queue_work(cmd_work)\nnci_unregister_device()          |\n  nci_close_device()             | ...\n    del_timer_sync(cmd_timer)[1] |\n...                              | Worker\nnci_free_device()                | nci_cmd_work()\n  kfree(ndev)[3]                 |   mod_timer(cmd_timer)[2]\n\nIn short, the cleanup routine thought that the cmd_timer has already\nbeen detached by [1] but the mod_timer can re-attach the timer [2], even\nit is already released [3], resulting in UAF.\n\nThis UAF is easy to trigger, crash trace by POC is like below\n\n[   66.703713] ==================================================================\n[   66.703974] BUG: KASAN: use-after-free in enqueue_timer+0x448/0x490\n[   66.703974] Write of size 8 at addr ffff888009fb7058 by task kworker/u4:1/33\n[   66.703974]\n[   66.703974] CPU: 1 PID: 33 Comm: kworker/u4:1 Not tainted 5.18.0-rc2 #5\n[   66.703974] Workqueue: nfc2_nci_cmd_wq nci_cmd_work\n[   66.703974] Call Trace:\n[   66.703974]  \u003cTASK\u003e\n[   66.703974]  dump_stack_lvl+0x57/0x7d\n[   66.703974]  print_report.cold+0x5e/0x5db\n[   66.703974]  ? enqueue_timer+0x448/0x490\n[   66.703974]  kasan_report+0xbe/0x1c0\n[   66.703974]  ? enqueue_timer+0x448/0x490\n[   66.703974]  enqueue_timer+0x448/0x490\n[   66.703974]  __mod_timer+0x5e6/0xb80\n[   66.703974]  ? mark_held_locks+0x9e/0xe0\n[   66.703974]  ? try_to_del_timer_sync+0xf0/0xf0\n[   66.703974]  ? lockdep_hardirqs_on_prepare+0x17b/0x410\n[   66.703974]  ? queue_work_on+0x61/0x80\n[   66.703974]  ? lockdep_hardirqs_on+0xbf/0x130\n[   66.703974]  process_one_work+0x8bb/0x1510\n[   66.703974]  ? lockdep_hardirqs_on_prepare+0x410/0x410\n[   66.703974]  ? pwq_dec_nr_in_flight+0x230/0x230\n[   66.703974]  ? rwlock_bug.part.0+0x90/0x90\n[   66.703974]  ? _raw_spin_lock_irq+0x41/0x50\n[   66.703974]  worker_thread+0x575/0x1190\n[   66.703974]  ? process_one_work+0x1510/0x1510\n[   66.703974]  kthread+0x2a0/0x340\n[   66.703974]  ? kthread_complete_and_exit+0x20/0x20\n[   66.703974]  ret_from_fork+0x22/0x30\n[   66.703974]  \u003c/TASK\u003e\n[   66.703974]\n[   66.703974] Allocated by task 267:\n[   66.703974]  kasan_save_stack+0x1e/0x40\n[   66.703974]  __kasan_kmalloc+0x81/0xa0\n[   66.703974]  nci_allocate_device+0xd3/0x390\n[   66.703974]  nfcmrvl_nci_register_dev+0x183/0x2c0\n[   66.703974]  nfcmrvl_nci_uart_open+0xf2/0x1dd\n[   66.703974]  nci_uart_tty_ioctl+0x2c3/0x4a0\n[   66.703974]  tty_ioctl+0x764/0x1310\n[   66.703974]  __x64_sys_ioctl+0x122/0x190\n[   66.703974]  do_syscall_64+0x3b/0x90\n[   66.703974]  entry_SYSCALL_64_after_hwframe+0x44/0xae\n[   66.703974]\n[   66.703974] Freed by task 406:\n[   66.703974]  kasan_save_stack+0x1e/0x40\n[   66.703974]  kasan_set_track+0x21/0x30\n[   66.703974]  kasan_set_free_info+0x20/0x30\n[   66.703974]  __kasan_slab_free+0x108/0x170\n[   66.703974]  kfree+0xb0/0x330\n[   66.703974]  nfcmrvl_nci_unregister_dev+0x90/0xd0\n[   66.703974]  nci_uart_tty_close+0xdf/0x180\n[   66.703974]  tty_ldisc_kill+0x73/0x110\n[   66.703974]  tty_ldisc_hangup+0x281/0x5b0\n[   66.703974]  __tty_hangup.part.0+0x431/0x890\n[   66.703974]  tty_release+0x3a8/0xc80\n[   66.703974]  __fput+0x1f0/0x8c0\n[   66.703974]  task_work_run+0xc9/0x170\n[   66.703974]  exit_to_user_mode_prepare+0x194/0x1a0\n[   66.703974]  syscall_exit_to_user_mode+0x19/0x50\n[   66.703974]  do_syscall_64+0x48/0x90\n[   66.703974]  entry_SYSCALL_64_after_hwframe+0x44/0x\n---truncated---"
