In the Linux kernel, the following vulnerability has been resolved:
USB: misc: uss720: unregister parport on probe failure
uss720 probe() registers a parport before reading the 1284 register used
to detect unsupported Belkin F5U002 adapters. If get 1284 register()
fails, the error path drops the driver private data and the USB device
reference, but leaves the parport device registered.
Leaving the port registered is more than a private allocation leak:
parport register port() has already reserved a parport number and
registered the parport bus device, while pp->private data still points at
the private data that the common error path is about to release.
Undo the pre-announce registration in the get 1284 register() failure
branch before jumping to the common private-data cleanup path. Clear
priv->pp first, matching the disconnect path and avoiding a stale pointer
in the private data.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.
