CVE-2026-64272 (GCVE-0-2026-64272)

Vulnerability from cvelistv5 – Published: 2026-07-25 08:49 – Updated: 2026-07-25 08:49

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.

GHSA-PRW5-9985-9RC7

Vulnerability from github – Published: 2026-07-25 12:31 – Updated: 2026-07-25 12:31

Details

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.

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: mms114 - fix touch indexing for MMS134S and MMS136\n\nThe MMS134S and MMS136 touch controllers have an event size of 6 bytes\nrather than 8 bytes. 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. However, the driver iterates through the\nevents using standard C array indexing (touch[index]), where each\nelement is sizeof(struct mms114_touch) (8 bytes) apart. As a result, any\ntouch events beyond the first one are read from incorrect offsets and\nparsed improperly.\n\nFix this by explicitly calculating the byte offset for each touch event\nbased on the device\u0027s specific event size.",
