CVE-2023-51426

Information leak via undisclosed type confusion

Published Dec 29, 2023 · Updated Aug 2, 2024

Type confusion in HONOR MagicOS 7.0 before 7.0.0.129 allows local users with high privileges to trigger an information leak. HONOR has not identified the affected component, the incompatible resource types, or the operation that mishandles them. Exploitation requires local high-privilege access; the vendor separately reports device service exceptions, so exposed data and service behavior remain unspecified.
