CVE-2024-32999

Local availability loss via undisclosed security-module flaw

Published May 11, 2024 · Updated Aug 2, 2024

Business logic error in Huawei HarmonyOS and EMUI allows local users to disrupt device availability through the OS security module. Huawei has not published the precise cracking condition or the incorrect operation that the module performs on attacker-controlled input. Local access without prior privileges is sufficient, and the documented consequence is loss of availability.
