Out-of-bounds read via FLP buffer overflow
Published Jan 16, 2024 · Updated Aug 29, 2024
Buffer overflow in the FLP module in Huawei HarmonyOS and EMUI allows remote attackers to trigger an out-of-bounds read. Huawei has not disclosed the affected function or how the FLP module copies untrusted input beyond a destination buffer. Network access without privileges or user interaction is sufficient; public material does not establish whether the read exposes data or only interrupts service.
