CVE-2024-54122

Service interruption via concurrent ability-module variable access

Published Dec 12, 2024 · Updated Dec 12, 2024

Race condition in the ability module in Huawei HarmonyOS 5.0.0 allows local users to interrupt service through concurrent variable access. The bulletin does not identify the shared variable, function, or missing synchronization operation beyond describing concurrent access in the ability module. NVD assesses local low-privileged access, no user interaction, and a high-complexity race, with the reported consequence limited to loss of availability.
