CVE-2026-63947: Bluetooth: HIDP: fix missing length checks in hidp_input_report()

Q: What access does an attacker need to trigger the issue?

The attacker needs to be a paired Bluetooth device capable of sending a truncated HIDP interrupt packet. No user interaction or local privileges are described.

Q: What could an affected system do when it receives a malformed packet?

The handler can read beyond the valid skb data. The out-of-bounds bytes may be interpreted as phantom keyboard input or spurious mouse movement.

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

Bluetooth: HIDP: fix missing length checks in hidpinputreport()

hidpinputreport() reads keyboard and mouse payload data from an skb without first verifying that skb->len contains enough data.

hidprecvintrframe() pulls the 1-byte HIDP header before dispatching to hidpinputreport(). If a paired device sends a truncated packet, the handler reads beyond the valid skb data, resulting in an out-of-bounds read of skb data. The OOB bytes may be interpreted as phantom key presses or spurious mouse movement.

Replace the open-coded length tracking and pointer arithmetic with skbpulldata() calls. skbpulldata() returns NULL if the requested bytes are not present, eliminating the need for a manual size variable and the separate skb->len guard.

Frequently Asked Questions

What access does an attacker need to trigger the issue?

The attacker needs to be a paired Bluetooth device capable of sending a truncated HIDP interrupt packet. No user interaction or local privileges are described.

What could an affected system do when it receives a malformed packet?

The handler can read beyond the valid skb data. The out-of-bounds bytes may be interpreted as phantom keyboard input or spurious mouse movement.
