CVE-2026-80754· NVD / CVE Program· CNA Linux

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

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0739c65e799d4a93fe573ed23255a71fcfcc5438, 6058f0fea10f3caf63a435677358d1b8e9325114, 6484e00d6778fdf2209cd75940bc3902b276457f.

Low priority for now. Upgrade to Linux Linux 0739c65e799d4a93fe573ed23255a71fcfcc5438, 6058f0fea10f3caf63a435677358d1b8e9325114, 6484e00d6778fdf2209cd75940bc3902b276457f or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
