CVE-2020-10831Public exploitNetwork attack vector

Malicious firmware loading via improper update verification

Published Mar 24, 2020 · Updated Aug 4, 2024

Improper firmware verification in Samsung mobile devices running Android 8.x, 9.0, or 10.0 allows attackers to load malicious touch-screen firmware. The touch-screen update path accepts firmware supplied through its kernel sysfs command interface without validating its authenticity. Public material does not establish the access needed to reach that path; demonstrated malformed firmware caused touch failures and I/O errors.
