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.
