Overview

CVE-2026-53340 is a medium-severity vulnerability. It was published on July 1, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
