CVE-2020-1808

Data disclosure or service interruption via buffer over-read

Published May 15, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Huawei and Honor smartphones allows local users to disclose data or interrupt service through a crafted application. Huawei has not identified the affected component or the operation that supplies the buffer length; it states only that software reads beyond the intended buffer. Exploitation requires a user to install the crafted application and is limited to disclosure of buffer-adjacent data or abnormal service behavior.
