Description
A flaw was found in the Linux kernel's i2c: imx driver. During runtime power management, an inconsistency between the clock and pinctrl states can occur. If the pinctrl state fails to switch to sleep mode after the clock is disabled, the clock remains off. This can lead to a system crash when the hardware attempts to access the disabled clock, resulting in a Denial of Service (DoS).
