Summary
Bluetooth: Avoid potential use-after-free in hci_error_reset
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: Avoid potential use-after-free in hcierrorreset

While handling the HCIEVHARDWAREERROR event, if the underlying BT controller is not responding, the GPIO reset mechanism would free the hcidev and lead to a use-after-free in hcierrorreset.

Here's the call trace observed on a ChromeOS device with Intel AX201: queueworkon+0x3e/0x6c __hcicmdsync_sk+0x2ee/0x4c0 [bluetooth <HASH:3b4a6>] ? initwaitentry+0x31/0x31 __hcicmdsync+0x16/0x20 [bluetooth <HASH:3b4a 6>] hcierrorreset+0x4f/0xa4 [bluetooth <HASH:3b4a 6>] processonework+0x1d8/0x33f workerthread+0x21b/0x373 kthread+0x13a/0x152 ? prcontwork+0x54/0x54 ? kthreadblkcg+0x31/0x31 retfromfork+0x1f/0x30

This patch holds the reference count on the hcidev while processing a HCIEVHARDWAREERROR event to avoid potential crash.
