The Linux kernel mms114 driver mishandled touch event data from MMS134S and MMS136 controllers due to a mismatch between the expected event size (8 bytes) and the actual event size (6 bytes). The driver used standard C array indexing assuming 8-byte intervals, resulting in incorrect offsets and improper parsing of events beyond the first. The vulnerability was resolved by explicitly calculating byte offsets based on the device's specific 6-byte event size, ensuring correct event indexing and parsing.

Improper parsing of touch events could cause incorrect touch input data to be processed by the system. The input data misinterpretation may affect device functionality relying on accurate touch input. There is no indication of code execution, privilege escalation, or data leakage from the provided information.

A fix has been implemented in the Linux kernel to explicitly calculate the correct byte offset for each touch event based on the device's event size. Users should update to the fixed kernel version containing this patch. Patch status is not explicitly confirmed; check the Linux kernel vendor advisory for the current remediation status and apply official fixes as available.
