Information disclosure via malformed GATT packet
Published Aug 8, 2023 · Updated Aug 2, 2024
Information disclosure in Qualcomm Snapdragon Bluetooth HOST allows remote authenticated users to read data by sending a crafted GATT packet. The Bluetooth HOST improperly validates a received GATT packet, but Qualcomm has not disclosed the affected parser or the data exposed. Reachability requires low privileges and no user interaction; the reported impact is limited to confidentiality.
