Bluetooth: btrtl: Avoid loading the config file on security chips

2025-12-12T17:40:20+00:00

[ Upstream commit cd8dbd9ef600435439bb0e70af0a1d9e2193aecb ]

For chips with security enabled, it's only possible to load firmware
with a valid signature pattern.
If key_id is not zero, it indicates a security chip, and the driver will
not load the config file.

- Example log for a security chip.

Bluetooth: btusb: mediatek: Avoid btusb_mtk_claim_iso_intf() NULL deref

2025-12-06T21:27:36+00:00

commit c884a0b27b4586e607431d86a1aa0bb4fb39169c upstream.

In btusb_mtk_setup(), we set `btmtk_data->isopkt_intf` to:
  usb_ifnum_to_if(data->udev, MTK_ISO_IFNUM)

That function can return NULL in some cases. Even when it returns
NULL, though, we still go on to call btusb_mtk_claim_iso_intf().

As of commit e9087e828827 ("Bluetooth: btusb: mediatek: Add locks for
usb_driver_claim_interface()"), calling btusb_mtk_claim_iso_intf()
when `btmtk_data->isopkt_intf` is NULL will cause a crash because
we'll end up passing a bad pointer to device_lock(). Prior to that
commit we'd pass the NULL pointer directly to
usb_driver_claim_interface() which would detect it and return an
error, which was handled.

Resolve the crash in btusb_mtk_claim_iso_intf() by adding a NULL check
at the start of the function. This makes the code handle a NULL
`btmtk_data->isopkt_intf` the same way it did before the problematic
commit (just with a slight change to the error message printed).

Bluetooth: btusb: mediatek: Fix kernel crash when releasing mtk iso interface

2025-12-06T21:27:30+00:00

[ Upstream commit 4015b979767125cf8a2233a145a3b3af78bfd8fb ]

When performing reset tests and encountering abnormal card drop issues
that lead to a kernel crash, it is necessary to perform a null check
before releasing resources to avoid attempting to release a null pointer.

Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF

2025-11-24T09:37:28+00:00

[ Upstream commit 23d22f2f71768034d6ef86168213843fc49bf550 ]

There is a KASAN: slab-use-after-free read in btusb_disconnect().
Calling "usb_driver_release_interface(&btusb_driver, data->intf)" will
free the btusb data associated with the interface. The same data is
then used later in the function, hence the UAF.

Fix by moving the accesses to btusb data to before the data is free'd.

Currently, bcsp_recv() can be called even when the BCSP protocol has not

the following stack trace:

Bluetooth: btusb: Check for unexpected bytes when defragmenting HCI frames

2025-11-13T20:37:33+00:00

[ Upstream commit 7722d6fb54e428a8f657fccf422095a8d7e2d72c ]

Some Barrot based USB Bluetooth dongles erroneously send one extra
random byte for the HCI_OP_READ_LOCAL_EXT_FEATURES command. The
consequence of that is that the next HCI transfer is misaligned by one
byte causing undefined behavior. In most cases the response event for
the next command fails with random error code.

Since the HCI_OP_READ_LOCAL_EXT_FEATURES command is used during HCI
controller initialization, the initialization fails rendering the USB
dongle not usable.
