 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:usb: typec: altmode should keep reference to parentThe altmode device release refers to its parent device, but without keepinga reference to it.When registering the altmode, get a reference to the parent and put it inthe release function.Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issueslike this:[   43.572860] kobject:  port0.0  (ffff8880057ba008): kobject_release, parent 0000000000000000 (delayed 3000)[   43.573532] kobject:  port0.1  (ffff8880057bd008): kobject_release, parent 0000000000000000 (delayed 1000)[   43.574407] kobject:  port0  (ffff8880057b9008): kobject_release, parent 0000000000000000 (delayed 3000)[   43.575059] kobject:  port1.0  (ffff8880057ca008): kobject_release, parent 0000000000000000 (delayed 4000)[   43.575908] kobject:  port1.1  (ffff8880057c9008): kobject_release, parent 0000000000000000 (delayed 4000)[   43.576908] kobject:  typec  (ffff8880062dbc00): kobject_release, parent 0000000000000000 (delayed 4000)[   43.577769] kobject:  port1  (ffff8880057bf008): kobject_release, parent 0000000000000000 (delayed 3000)[   46.612867] ==================================================================[   46.613402] BUG: KASAN: slab-use-after-free in typec_altmode_release+0x38/0x129[   46.614003] Read of size 8 at addr ffff8880057b9118 by task kworker/2:1/48[   46.614538][   46.614668] CPU: 2 UID: 0 PID: 48 Comm: kworker/2:1 Not tainted 6.12.0-rc1-00138-gedbae730ad31 #535[   46.615391] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.15.0-1 04/01/2014[   46.616042] Workqueue: events kobject_delayed_cleanup[   46.616446] Call Trace:[   46.616648]  <TASK>[   46.616820]  dump_stack_lvl+0x5b/0x7c[   46.617112]  ? typec_altmode_release+0x38/0x129[   46.617470]  print_report+0x14c/0x49e[   46.617769]  ? rcu_read_unlock_sched+0x56/0x69[   46.618117]  ? __virt_addr_valid+0x19a/0x1ab[   46.618456]  ? kmem_cache_debug_flags+0xc/0x1d[   46.618807]  ? typec_altmode_release+0x38/0x129[   46.619161]  kasan_report+0x8d/0xb4[   46.619447]  ? typec_altmode_release+0x38/0x129[   46.619809]  ? process_scheduled_works+0x3cb/0x85f[   46.620185]  typec_altmode_release+0x38/0x129[   46.620537]  ? process_scheduled_works+0x3cb/0x85f[   46.620907]  device_release+0xaf/0xf2[   46.621206]  kobject_delayed_cleanup+0x13b/0x17a[   46.621584]  process_scheduled_works+0x4f6/0x85f[   46.621955]  ? __pfx_process_scheduled_works+0x10/0x10[   46.622353]  ? hlock_class+0x31/0x9a[   46.622647]  ? lock_acquired+0x361/0x3c3[   46.622956]  ? move_linked_works+0x46/0x7d[   46.623277]  worker_thread+0x1ce/0x291[   46.623582]  ? __kthread_parkme+0xc8/0xdf[   46.623900]  ? __pfx_worker_thread+0x10/0x10[   46.624236]  kthread+0x17e/0x190[   46.624501]  ? kthread+0xfb/0x190[   46.624756]  ? __pfx_kthread+0x10/0x10[   46.625015]  ret_from_fork+0x20/0x40[   46.625268]  ? __pfx_kthread+0x10/0x10[   46.625532]  ret_from_fork_asm+0x1a/0x30[   46.625805]  </TASK>[   46.625953][   46.626056] Allocated by task 678:[   46.626287]  kasan_save_stack+0x24/0x44[   46.626555]  kasan_save_track+0x14/0x2d[   46.626811]  __kasan_kmalloc+0x3f/0x4d[   46.627049]  __kmalloc_noprof+0x1bf/0x1f0[   46.627362]  typec_register_port+0x23/0x491[   46.627698]  cros_typec_probe+0x634/0xbb6[   46.628026]  platform_probe+0x47/0x8c[   46.628311]  really_probe+0x20a/0x47d[   46.628605]  device_driver_attach+0x39/0x72[   46.628940]  bind_store+0x87/0xd7[   46.629213]  kernfs_fop_write_iter+0x1aa/0x218[   46.629574]  vfs_write+0x1d6/0x29b[   46.629856]  ksys_write+0xcd/0x13b[   46.630128]  do_syscall_64+0xd4/0x139[   46.630420]  entry_SYSCALL_64_after_hwframe+0x76/0x7e[   46.630820][   46.630946] Freed by task 48:[   46.631182]  kasan_save_stack+0x24/0x44[   46.631493]  kasan_save_track+0x14/0x2d[   46.631799]  kasan_save_free_info+0x3f/0x4d[   46.632144]  __kasan_slab_free+0x37/0x45[   46.632474]---truncated---

CVE-2024-50150

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

usb: typec: altmode should keep reference to parent

The altmode device release refers to its parent device, but without keeping
a reference to it.

When registering the altmode, get a reference to the parent and put it in
the release function.

Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issues
like this:

CVE-2024-50150

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

usb: typec: altmode should keep reference to parent

The altmode device release refers to its parent device, but without keeping
a reference to it.

When registering the altmode, get a reference to the parent and put it in
the release function.

Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issues
like this:

CVE-2024-50150

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

usb: typec: altmode should keep reference to parent

The altmode device release refers to its parent device, but without keeping
a reference to it.

When registering the altmode, get a reference to the parent and put it in
the release function.

Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issues
like this:
