Vulnerability from github – Published: 2026-07-01 15:35 – Updated: 2026-07-01 15:35

Details

In the Linux kernel, the following vulnerability has been resolved:

i2c: imx: fix clock and pinctrl state inconsistency in runtime PM

In i2c_imx_runtime_suspend(), the clock is disabled before switching the pinctrl state to sleep. If pinctrl_pm_select_sleep_state() fails, the runtime suspend is aborted but the clock remains disabled, causing a system crash when the hardware is subsequently accessed.

Fix this by switching the pinctrl state before disabling the clock so that a pinctrl failure leaves the clock enabled and the hardware accessible.

In i2c_imx_runtime_resume(), restore the pinctrl state back to sleep if clk_enable() fails to keep the consistent.
