Buffer overflow via sec_ts sysfs race
Published Apr 7, 2020 · Updated Aug 5, 2024
Race condition in the sec_ts touchscreen sysfs interface on Samsung devices with Android 6.0 or 7.0 allows attackers to trigger a buffer overflow. The interface performs a buffer copy without consistently validating source and destination sizes during concurrent sysfs operations. Linux file permissions restrict access to the interface, and public sources do not specify whether the overflow enables code execution, data access, or only a crash.
