Official 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().

Technical Analysis

CVE-2026-31745 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
