kernel: usb: gadget: net2280: Fix double free in probe error path
    </Bugzilla>
    <CWE>CWE-1341</CWE>
    <Details xml:lang="en:us" source="Mitre">
In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: net2280: Fix double free in probe error path

usb_initialize_gadget() installs gadget_release() as the release
callback for the embedded gadget device.  The struct net2280 instance is
therefore released through gadget_release() when the gadget device's last
reference is dropped.

The probe error path calls net2280_remove(), which tears down the
partially initialized device and drops the gadget reference with
usb_put_gadget().  Calling kfree(dev) afterwards can free the same object
again.

Drop the explicit kfree() and let the gadget device release callback
handle the final free.  This issue was found by a static analysis tool
I am developing.

    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in the Linux kernel's USB gadget net2280 driver. This vulnerability occurs due to a double free error in the probe error path. When a gadget device is being initialized, an error can cause the device to be freed twice, leading to memory corruption. This can result in a denial of service, making the system unstable or unresponsive.
