Local information disclosure via freed Bluetooth buffer logging
Published Aug 26, 2025 · Updated Aug 27, 2025
Use-after-free in Android 15's Bluetooth HID stack allows local users to disclose process memory without user interaction. hidd_check_config_done passes hd_cb.pending_data to L2CA_DataWrite, then reads its len field for failure logging after the call can free the buffer. Low-privileged local access is required, and the demonstrated consequence is confidentiality loss rather than code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
