Service interruption via kernel drop-detection buffer overflow
Published Aug 6, 2025 · Updated Aug 6, 2025
Buffer overflow in Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 and 14.0.0 allows local users to interrupt service. The kernel drop detection module fails to verify data before processing it, causing a buffer overflow; Huawei has not disclosed the specific input path or memory operation. Exploitation requires local access and high privileges, and the documented consequence is limited to loss of availability.
