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's specific event size.\n\n## Affected\n\n- `linux_kernel >= 5.13, < 6.6.145`\n- `linux_kernel >= 6.7, < 6.12.96`\n- `linux_kernel >= 6.13, < 6.18.39`\n- `linux_kernel >= 6.19, < 7.1.4`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 7.1.4`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
