CVE-2022-48354

Bluetooth service crash via heap out-of-bounds write

Published Mar 27, 2023 · Updated Feb 20, 2025

Heap out-of-bounds write in Huawei HarmonyOS and EMUI allows physically proximate attackers to crash the Bluetooth process. The public bulletins identify the Bluetooth module and an out-of-bounds heap write but do not disclose the malformed input, code path, or erroneous write operation. Exploitation requires Bluetooth-range proximity and interrupts Bluetooth service by crashing its process; no confidentiality or integrity impact is reported.
