Hello: This patch was applied to bluetooth/bluetooth-next.git (master) by Luiz Augusto von Dentz [off-list ref]: On Wed, 20 May 2026 18:56:43 -0400 you wrote:
hidp_input_report() reads keyboard and mouse payload data from an skb without first verifying that skb->len contains enough data. hidp_recv_intr_frame() pulls the 1-byte HIDP header before dispatching to hidp_input_report(). 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. [...]
