CVE-2023-23443

Information leak via type confusion

Published Dec 29, 2023 · Updated Apr 17, 2025

Type confusion in HONOR MagicOS 7.0 before 7.0.0.156 allows local users to obtain information via unspecified vectors. HONOR does not disclose the component or operation that mishandles an input type, so the precise mechanism remains unpublished. Local low-privilege access is required; successful exploitation can leak information and trigger device service exceptions, with no documented remote path.
