CVE-2026-64274

System crash via unclamped touchscreen contact count

Published Jul 25, 2026 · Updated Jul 25, 2026

An out-of-bounds write in the Linux Kernel Goodix touchscreen driver allows physically proximate attackers to crash systems via I2C. goodix_ts_read_input_report() trusts the controller's four-bit maximum-contact field, accepts as many as 15 contacts, and lets goodix_i2c_read() write up to 45 bytes beyond the 92-byte point_data stack buffer. Exploitation requires a malicious or counterfeit controller or physical access to tamper with the I2C bus; the documented consequence is a kernel crash.
