CVE-2026-53340

Local system crash via runtime PM state inconsistency

Published Jul 1, 2026 · Updated Jul 1, 2026

Availability flaw in the IMX I2C driver in Linux Kernel 6.14 allows local users to crash the system during runtime suspend. The i2c_imx_runtime_suspend() path disables the controller clock before selecting the sleep pinctrl state, so a failed pinctrl transition leaves the hardware inaccessible. A low-privilege local context and a failing sleep-state selection are required; later hardware access triggers a system crash without reported data exposure or modification.
