Pending analysis
Type:
CWE-415 Double Free
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> reset: gpio: fix double free in reset_add_gpio_aux_device() error path<br /> <br /> When __auxiliary_device_add() fails, reset_add_gpio_aux_device()<br /> calls auxiliary_device_uninit(adev).<br /> <br /> The device release callback reset_gpio_aux_device_release() frees<br /> adev, but the current error path then calls kfree(adev) again,<br /> causing a double free.<br /> <br /> Keep kfree(adev) for the auxiliary_device_init() failure path, but<br /> avoid freeing adev after auxiliary_device_uninit().
