CVE-2020-9211

Service interruption via insufficient configuration input validation

Published Dec 27, 2024 · Updated Dec 27, 2024

Out-of-bounds read and write in Huawei Mate 30 10.1.0.126(C00E125R5P3) allows local users to interrupt device operation. An unnamed module insufficiently validates data obtained after a configuration file is modified before performing memory access. Exploitation requires permission to modify that file, and Huawei has not disclosed the module, field, or malformed value involved.
