CVE-2023-46762Network attack vector

Process crashes via kernel driver out-of-bounds write

Published Nov 8, 2023 · Updated Sep 4, 2024

An out-of-bounds write in Huawei EMUI 13.0.0 and HarmonyOS 3.0.0, 3.1.0, and 4.0.0 allows remote attackers to crash processes. Huawei identifies the locus only as a kernel driver module and has not published the affected driver, entry point, or malformed input that causes the write beyond its buffer boundary. The public record does not state the delivery path; the documented consequence is limited to process exceptions rather than device compromise.
