Description OSIDB Bzimport 2026-03-25 11:03:31 UTC 
In the Linux kernel, the following vulnerability has been resolved:

nfc: pn533: properly drop the usb interface reference on disconnect

When the device is disconnected from the driver, there is a "dangling"
reference count on the usb interface that was grabbed in the probe
callback.  Fix this up by properly dropping the reference after we are
done with it.
