clk: qcom: camcc-sc8280xp: unregister CAMCC_GDSC_CLK
With the introduction of sync_state support in the clk and pmdomain
subsystems, the following warning happens when the unused clocks are
shutdown in camcc-sc8280xp:

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MSFT: validate evt_prefix_len against the response length
read_supported_features() only checks that the response covers the fixed
part of struct msft_rp_read_supported_features, which is 11 bytes:
if (skb->len < sizeof(*rp)) {
bt_dev_err(hdev, "MSFT supported features length mismatch");
goto failed;
}
evt_prefix[] is a flexible array member and rp->evt_prefix_len is an
unvalidated u8 taken straight out of that response, so
msft->evt_prefix = kmemdup(rp->evt_prefix, rp->evt_prefix_len,
GFP_KERNEL);
copies up to 255 bytes from a reply that may have carried none of them.
What is copied is data the controller never sent, and it is then used to
match incoming vendor events in msft_vendor_evt().
This is not an out-of-bounds access. An skb data allocation always has
at least SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) bytes past the
payload, which is more than the 255 byte maximum, so the read stays
inside the allocation and KASAN does not report it. It is still a read
of bytes the host was never given, with the length fully controlled by
the controller.
Reject a response that is too short for the prefix it declares.
Verified with an emulated controller over /dev/vhci on a KASAN kernel,
with vhci made to advertise an MSFT opcode the way btintel, btqca, btmtk
and btrtl do unconditionally. A reply of exactly 11 bytes declaring
evt_prefix_len = 255 reaches kmemdup and copies 255 bytes
("skb->len=11 evt_prefix_len=255", with the copied buffer dumped); since
the reply ends at the fixed part, all 255 come from past the end of the
response. No KASAN report is produced, as expected from the allocation
slack described above. With this patch the response is rejected with
"MSFT event prefix length mismatch" and msft->evt_prefix is left unset. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: free the HCI command when it is cancelled
mgmt_hci_cmd_sync() queues the pending command with a NULL destroy
callback, so it is only freed if send_hci_cmd_sync() runs. A cancelled
entry is leaked, as _hci_cmd_sync_cancel_entry() does not release
entry->data when there is no destroy callback, and hci_cmd_sync_clear()
cancels every pending entry when the controller is unregistered. Nothing
else reclaims it either: mgmt_pending_new() does not put the command on
hdev->mgmt_pending.
The leak also pins the socket reference taken by mgmt_pending_new(), so
the mgmt socket is never released.
Free the command from a destroy callback. The now-empty done label is
replaced by a direct return. |

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: free the advertising instance on the failure and cancel paths
adv_timeout_expire() hands a kmalloc()ed instance byte to
hci_cmd_sync_queue() with a NULL destroy callback, and only
adv_timeout_expire_sync() frees it. That leaks on two paths:
- the return value is not checked, and hci_cmd_sync_queue() does not
take ownership when it fails (-ENETDOWN, -ENODEV, -ENOMEM);
- a cancelled entry is not released, as _hci_cmd_sync_cancel_entry()
does not free entry->data when there is no destroy callback.
hci_cmd_sync_clear() cancels every pending entry when the controller
is unregistered.
Free the buffer from a destroy callback, and in the caller when the entry
could not be queued at all. |
| TCH QRing smart ring model R20_B006 running firmware RT09R20_1.00.00_250318 contains an unauthenticated Bluetooth Low Energy access vulnerability that allows any nearby attacker to connect to the device without pairing, authentication, or user approval by exploiting the exposed Nordic UART Service which enforces no client authentication or command authorization. Attackers within Bluetooth Low Energy range can connect directly to the ring, bypassing the official application and cloud authentication, to read battery levels, activate live heart rate monitoring, and retrieve stored historical heart rate and blood oxygen records. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: wacom: validate report length in wacom_intuos_pro2_bt_irq
wacom_intuos_pro2_bt_irq() receives the wire report length in `len`
but never consults it before parsing. After the report-id gate it
unconditionally calls wacom_intuos_pro2_bt_pen() and then, selected by
features.type, a fixed chain of sub-parsers, none of which receive
`len`:
wacom_intuos_pro2_bt_pen(wacom);
if (type == INTUOSP2_BT || type == INTUOSP2S_BT) {
wacom_intuos_pro2_bt_touch(wacom);
wacom_intuos_pro2_bt_pad(wacom);
wacom_intuos_pro2_bt_battery(wacom);
} else {
wacom_intuos_gen3_bt_pad(wacom);
wacom_intuos_gen3_bt_battery(wacom);
}
Each sub-parser dereferences wacom->data at fixed offsets. The furthest
byte touched on each branch is:
INTUOSP2_BT / INTUOSP2S_BT: wacom_intuos_pro2_bt_pad() reads data[285]
(the touchring byte), so the report must be at least 286 bytes;
INTUOSHT3_BT ("gen3"): wacom_intuos_gen3_bt_battery() reads data[45],
so the report must be at least 46 bytes.
features.type is selected from the VID/PID id_table entry and
wacom_setup_device_quirks() force-registers the pen/pad/touch inputs
for that type independent of the report descriptor, so a malicious or
malfunctioning paired/spoofed Bluetooth peripheral can advertise that
VID/PID and send an undersized report that still satisfies the
data[0] == 0x80/0x81 gate. The driver then reads past the received
report and forwards the bytes to userspace via evdev (MSC_SERIAL /
ABS_MISC / ABS_WHEEL on the pen and pad input nodes), an out-of-bounds
read with a concrete userspace read-back channel, and a true
out-of-bounds read on transports whose backing buffer is sized to the
(small) report descriptor rather than a fixed-size staging buffer.
This is the same class of bug commit 2f1763f62909 ("HID: wacom: fix
out-of-bounds read in wacom_intuos_bt_irq") already hardened in the
sibling wacom_intuos_bt_irq(), which guards each report id against its
minimum length before parsing.
Guard wacom_intuos_pro2_bt_irq() the same way: before parsing, reject
reports shorter than the furthest offset the selected branch actually
dereferences, warn, and bail out. Because the whole pen/touch/pad/
battery chain runs unconditionally per branch, a single up-front check
against the maximum offset (286 bytes for INTUOSP2_BT/INTUOSP2S_BT,
46 bytes for the gen3 branch) bounds every sub-parser. Returning 0 on
a short report also skips those calls for the same malformed report,
which is the safe, conservative behavior. |

| BlueZ A2DP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.
The specific flaw exists within the handling of the stream endpoints. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29429. |
| ArduinoBLE enables Bluetooth Low Energy connectivity on certain Arduino models. Versions prior to 2.0.2 contain a missing bounds check in the ATT layer write request handler that allows a remote, unauthenticated BLE client to corrupt memory in the ATTClass global object. Devices running ArduinoBLE with one or more characteristics configured with the BLEEncryption property are affected. The fix is included starting from the 2.0.2 release. |
| In writeToParcel of BleRssiRangingCapabilities.java, there is a possible way to obtain the Bluetooth MAC address due to a missing permission check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |
| The mcumgr SMP settings-management group handlers settings_mgmt_read(), settings_mgmt_write(), and settings_mgmt_delete() in subsys/mgmt/mcumgr/grp/settings_mgmt/src/settings_mgmt.c allocate a key_name buffer (and, for read, a data buffer) via k_malloc() when CONFIG_MCUMGR_GRP_SETTINGS_BUFFER_TYPE_HEAP is enabled, relying on the end: label to k_free() them. When CONFIG_MCUMGR_GRP_SETTINGS_ACCESS_HOOK is also enabled and the application access hook rejects a request by returning status MGMT_CB_ERROR_RC, the handler executed return ret_rc; directly, bypassing end: and leaking the heap allocation on every rejected request.
The settings handlers are reachable over the unauthenticated SMP transport (Bluetooth LE, UART, or UDP, depending on product configuration). The access hook is the mechanism applications use to deny unauthorized settings access, and MGMT_CB_ERROR_RC is a common rejection style, so an attacker who can send settings read/write/delete commands that the hook rejects triggers a heap leak on each attempt.
Because the leaked memory is never reclaimed until reboot, a sustained stream of rejected requests monotonically exhausts the kernel heap until k_malloc() fails, denying mcumgr service and impacting any other heap consumer on the device — a denial of service. The impact is availability-only; there is no memory corruption or information disclosure. Only configurations that select the heap buffer type, enable the access hook, and register a hook that returns MGMT_CB_ERROR_RC are affected (the default stack buffer type cannot leak). |

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: eir: Fix OOB read in eir_get_service_data()
eir_get_service_data() walks the advertising data for a Service Data
field with a matching UUID. On a mismatch it advances:
eir += dlen;
eir_len -= dlen;
eir_get_data() reports dlen as the field's data length, but the field
spans dlen + 2 bytes once its length and type bytes count, and more
when non-Service-Data fields were skipped to reach it. The pointer
lands correctly on the next field. eir_len does not, and the shortfall
compounds across fields until eir_get_data() reads the length and type
bytes of a "field" past the end of the buffer.
For an ISO broadcast sink that buffer is hcon->le_per_adv_data[], filled
from the periodic advertising reports of a remote broadcaster. A PA
payload packed with mismatching Service Data fields walks off the array
into the rest of struct hci_conn. A drifted field that matches the BAA
UUID puts those bytes in iso_pi(sk)->base, where user space reads them
back with getsockopt(BT_ISO_BASE).
Recompute eir_len from the end of the buffer each iteration. |
