CVE-2023-46767Network attack vector

Service interruption via kernel driver out-of-bounds write

Published Nov 8, 2023 · Updated Sep 4, 2024

Kernel-driver out-of-bounds write in Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote attackers to trigger process exceptions. Huawei has not disclosed the affected driver, the attacker-controlled input, or the bounds-checking error that permits the write. The reported consequence is limited to process exceptions that interrupt availability; arbitrary code execution is not reported.
