CVE-2026-64275: Input: elan_i2c - prevent division by zero and arithmetic underflow

Published Jul 25, 2026

In the Linux kernel, the following vulnerability has been resolved:

Input: elani2c - prevent division by zero and arithmetic underflow

The Elan I2C touchpad driver queries the device for its physical dimensions and trace counts to calculate the device resolution and width. However, if the device firmware or device tree provides invalid zero values for xtraces or ytraces, it results in a fatal division-by-zero exception leading to a kernel panic during device probe.

Add checks to ensure these parameters are non-zero before performing the division. If invalid trace values are detected, fall back to a safe default of 1.

Additionally, prevent an arithmetic underflow in the touch reporting logic. Previously, if the calculated or fallback width was smaller than ETPFWIDTHREDUCE (90), the subtraction would underflow, resulting in a massive unsigned integer being reported to userspace. Clamp the adjusted width to a minimum of 0 to safely handle small physical dimensions and fallback scenarios.

Completing the probe with safe fallback values ensures the sysfs nodes are created, keeping the firmware update path intact so a recovery firmware can be flashed to the device.

  101. Compensating control

    Clamp the adjusted touch-reporting width to a minimum of 0 before subtracting ETP_FWIDTH_REDUCE (90), preventing arithmetic underflow for small physical dimensions or fallback values.
