CVE-2024-54115Network attack vector

Service interruption via DASH out-of-bounds read

Published Dec 12, 2024 · Updated Dec 12, 2024

Out-of-bounds read in the DASH module in Huawei HarmonyOS 5.0.0 allows remote attackers to interrupt service via unspecified vectors. Huawei has not disclosed the affected function, unchecked boundary operation, or exact DASH input that causes a read beyond the intended buffer. Exploitation requires user interaction and affects availability only; published material does not identify whether the result is playback failure, a process crash, or wider device interruption.
