Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: Input: mms114 - fix touch indexing for MMS134S and MMS136 The MMS134S and MMS136 touch controllers have an event size of 6 bytes rather than 8 bytes. When __mms114_read_reg() reads the touch data packet from the device into the touch buffer, the events are packed tightly at 6-byte intervals. However, the driver iterates through the events using standard C array indexing (touch[index]), where each element is sizeof(struct mms114_touch) (8 bytes) apart. As a result, any touch events beyond the first one are read from incorrect offsets and parsed improperly. Fix this by explicitly calculating the byte offset for each touch event based on the device's specific event size.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Upgrade available Upgrade to 6.6.145 / 6.12.96 / 6.18.39 or later
Fixed in 6.6.1456.12.966.18.39
Recommended fix High confidence

Linux Kernel 7.1.4 (or the latest stable version in your kernel branch that includes the fix: 6.6.145, 6.12.96, or 6.18.39)

  1. Identify the currently running kernel version using 'uname -r'
  2. Download or obtain the appropriate kernel package for your distribution that includes version 6.6.145, 6.12.96, 6.18.39, or 7.1.4 (whichever is the latest available for your branch)
  3. Apply the kernel upgrade following your distribution's standard procedures (e.g., 'apt-get update && apt-get upgrade' for Debian/Ubuntu, or 'yum/dnf update' for RHEL/Fedora)
  4. Reboot the system to load the new kernel
  5. Verify the new kernel version is running with 'uname -r' and confirm the version includes the fix (>= 6.6.145, >= 6.12.96, >= 6.18.39, or >= 7.1.4 depending on your branch)
Caveat Kernel upgrades may require rebuilding out-of-tree kernel modules; ensure proprietary drivers (GPU, WiFi, etc.) are compatible with the new version before upgrading in production environments
