Transient denial of service via GATT buffer over-read
Published Jan 2, 2024 · Updated Aug 2, 2024
Buffer over-read in Qualcomm Snapdragon QCN7606 firmware allows remote attackers to cause a transient service interruption via GATT data. The GATT service-data parser calculates memory needed for multiple services beyond the actual services-buffer size and reads past that buffer. No authentication or user interaction is required, and the documented consequence is transient denial of service without data disclosure or modification.
