CVE-2020-1805

Information disclosure or disruption via unchecked driver parameters

Published Apr 27, 2020 · Updated Aug 4, 2024

Out-of-bounds reads in an Honor V10 driver before 10.0.0.156(C00E156R2P4) allow attackers to disclose data or disrupt service. The driver fails to validate parameters supplied by a crafted application and reads several bytes beyond the intended buffer. Exploitation requires a user to install the crafted application; Huawei reports only information disclosure or abnormal service behavior.
