CVE-2017-18693Network attack vector

Memory corruption via fps sysfs entry overflow

Published Apr 7, 2020 · Updated Aug 5, 2024

Buffer overflow in Samsung mobile devices running Android 4.4 through 7.0 allows remote attackers to corrupt memory through the fps sysfs entry. Samsung has not published the affected function or the unchecked operation that allows input written through the fps entry to exceed its destination buffer. NVD assesses unauthenticated network reachability, but the public record establishes memory corruption only and does not confirm code execution or a device crash.
