CVE-2017-18671Network attack vector

System-process crash via mishandled Wi-Fi intents

Published Apr 7, 2020 · Updated Aug 5, 2024

Improper exception handling in Wi-Fi intents on Samsung mobile devices with Android 5.0 through 7.x allows remote attackers to crash system processes. The published record identifies Wi-Fi-related intents as the locus but does not disclose the affected handler or the exception that escapes it. Network reachability and no prior privileges are required; successful delivery interrupts availability by terminating system processes, with no reported data disclosure or modification.
