Title
Input: mms114 - fix touch indexing for MMS134S and MMS136
Summary
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.

When __mms114_read_reg() reads the touch data\npacket from the device into the touch buffer, the events are packed\ntightly at 6-byte intervals.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
