Overview

CVE-2026-74461 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

i2c: imx: Cancel hrtimer before clearing slave pointer

In i2c_imx_unreg_slave(), the slave pointer is set to NULL after

disabling interrupts. However, a pending interrupt might already

have started the hrtimer (i2c_imx_slave_timeout) before the pointer

was cleared. If the hrtimer fires after i2c_imx->slave is set to

NULL, the timer callback i2c_imx_slave_finish_op() will call

i2c_imx_slave_event() with a NULL slave pointer, which results in a

use-after-free / NULL pointer dereference.

Fix by canceling the hrtimer and waiting for it to complete after

disabling interrupts, before clearing the slave pointer.

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.
