What to Know

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

Input: synaptics-rmi4 - fix F55 transmitter electrode count typo

During F55 sensor detection, the transmitter (TX) electrode count was

incorrectly assigned the value of the receiver (RX) electrode count

due to copy-paste typos.

This incorrect value was then propagated to the driver data and used

by F54 to determine the diagnostics report size. On devices with more

RX than TX electrodes, this inflated the perceived TX count, leading

to incorrect report size calculations and potential out-of-bounds

buffer accesses.

Fix the typos by correctly assigning the TX electrode counts. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
