CVE-2017-18674Network attack vector

Unauthenticated kernel panic via Timaservice

Published Apr 7, 2020 · Updated Aug 5, 2024

Improper input validation in Samsung mobile devices running Android 7.0 allows remote attackers to trigger a kernel panic in Timaservice. Samsung and MITRE have not published the input, interface, or faulty operation within Timaservice that causes the panic. Network access without authentication or user interaction is sufficient, and successful exploitation crashes the device kernel.
