CVE-2026-63908 — Input: atmel_mxt_ts - fix boundary check in mxt_prepare_cfg_mem

In the Linux kernel, the following vulnerability has been resolved: Input: atmel_mxt_ts - fix boundary check in mxt_prepare_cfg_mem When a configuration file provides an object size that is larger than the driver's known mxt_obj_size(object), the driver intends to discard the extra bytes. The loop iterates using for (i = 0; i < size; i++). Inside the loop, the condition to skip processing extra bytes is: if (i > mxt_obj_size(object)) continue; Since i is a 0-based index, the valid indices for the object are 0 through mxt_obj_size(object) - 1. When i == mxt_obj_size(object), the condition evaluates to false, and the code processes the byte instead of discarding it. This causes the code to calculate byte_offset = reg + i - cfg->start_ofs and writes the byte there, overwriting exactly one byte of the adjacent instance or object. Update the boundary check to skip extra bytes correctly by using >=.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+2

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
