Service interruption via clock-module NULL-pointer access
Published May 11, 2024 · Updated Aug 2, 2024
NULL-pointer access in the clock module in Huawei HarmonyOS and EMUI allows local users to interrupt service through an undisclosed trigger. Huawei does not disclose the clock-module code path, input, or operation that causes the NULL-pointer access. Local access without privileges or user interaction is sufficient; the bulletin names availability impact, while Huawei's CVSS assessment also scores limited confidentiality and integrity impact.
