CVE-2017-18694Network attack vector

Kernel-address disclosure via incorrect log format specifier

Published Apr 7, 2020 · Updated Aug 5, 2024

Information disclosure in Samsung mobile software through 2016-10-25 on Exynos5 devices allows attackers to read kernel addresses from logs. A kernel logging call uses an incorrect format specifier, causing address values to be written to the log instead of the intended data. Exposure requires affected Exynos5 hardware and access to the resulting logs; the published record reports address disclosure only, not data modification or service interruption.
