 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:usb: hub: Guard against accesses to uninitialized BOS descriptorsMany functions in drivers/usb/core/hub.c and drivers/usb/core/hub.haccess fields inside udev->bos without checking if it was allocated andinitialized. If usb_get_bos_descriptor() fails for whateverreason, udev->bos will be NULL and those accesses will result in acrash:BUG: kernel NULL pointer dereference, address: 0000000000000018PGD 0 P4D 0Oops: 0000 [#1] PREEMPT SMP NOPTICPU: 5 PID: 17818 Comm: kworker/5:1 Tainted: G W 5.15.108-18910-gab0e1cb584e1 #1 <HASH:1f9e 1>Hardware name: Google Kindred/Kindred, BIOS Google_Kindred.12672.413.0 02/03/2021Workqueue: usb_hub_wq hub_eventRIP: 0010:hub_port_reset+0x193/0x788Code: 89 f7 e8 20 f7 15 00 48 8b 43 08 80 b8 96 03 00 00 03 75 36 0f b7 88 92 03 00 00 81 f9 10 03 00 00 72 27 48 8b 80 a8 03 00 00 <48> 83 78 18 00 74 19 48 89 df 48 8b 75 b0 ba 02 00 00 00 4c 89 e9RSP: 0018:ffffab740c53fcf8 EFLAGS: 00010246RAX: 0000000000000000 RBX: ffffa1bc5f678000 RCX: 0000000000000310RDX: fffffffffffffdff RSI: 0000000000000286 RDI: ffffa1be9655b840RBP: ffffab740c53fd70 R08: 00001b7d5edaa20c R09: ffffffffb005e060R10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000000R13: ffffab740c53fd3e R14: 0000000000000032 R15: 0000000000000000FS: 0000000000000000(0000) GS:ffffa1be96540000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000000000000018 CR3: 000000022e80c005 CR4: 00000000003706e0Call Trace:hub_event+0x73f/0x156e? hub_activate+0x5b7/0x68fprocess_one_work+0x1a2/0x487worker_thread+0x11a/0x288kthread+0x13a/0x152? process_one_work+0x487/0x487? kthread_associate_blkcg+0x70/0x70ret_from_fork+0x1f/0x30Fall back to a default behavior if the BOS descriptor isn t accessibleand skip all the functionalities that depend on it: LPM support checks,Super Speed capabilitiy checks, U1/U2 states setup.
