Memory corruption via unchecked Bluetooth command length
Published Sep 2, 2022 · Updated Aug 3, 2024
Stack-based buffer overflow in Qualcomm Snapdragon Bluetooth HOST allows remote attackers to corrupt memory via a crafted command. The HOST extraction path uses the command length parameter without adequately bounding data written to a stack buffer, allowing input to exceed the destination. No authentication or user interaction is required; Qualcomm reports memory corruption but does not disclose whether exploitation yields code execution or only a crash.
