CVE-2025-58311

Information disclosure and service interruption via USB UAF

Published Nov 28, 2025 · Updated Nov 28, 2025

Use-after-free in the USB driver module of affected Huawei HarmonyOS and EMUI releases allows local users to interrupt service and expose information. Huawei has not published the memory object's identity, the code locus that frees it, or the operation that later dereferences the stale pointer. Exploitation requires high privileges, high complexity, and user interaction; successful exploitation is bounded to confidentiality loss and service interruption.
