What happened

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.

Continue reading

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.

Evidence summary (plain text)

Linux kernel: usb: gadget: net2280: Fix double free in probe error path (Jul 24, 2026).
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.

About this data

This record was ingested from a data source. Retrieved: Nov 8, 2026, 20:31 UTC. Ingestion is not an independent editorial investigation.

NVD status: Analyzed. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
