Vulnerability Details CVE-2026-31745
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().
