Overview

CVE-2026-31745 is a high-severity vulnerability. It was published on May 1, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

reset: gpio: fix double free in reset_add_gpio_aux_device() error path

When __auxiliary_device_add() fails, reset_add_gpio_aux_device()

calls auxiliary_device_uninit(adev).

The device release callback reset_gpio_aux_device_release() frees

adev, but the current error path then calls kfree(adev) again,

causing a double free.

Keep kfree(adev) for the auxiliary_device_init() failure path, but

avoid freeing adev after auxiliary_device_uninit().

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.
