In the Linux kernel, the following vulnerability has been resolved: comedi: c6xdigio: Fix invalid PNP driver unregistration The Comedi low-level driver "c6xdigio" seems to be for a parallel port connected device. When the Comedi core calls the driver's Comedi "attach" handler to configure a Comedi to use this driver, it tries to enable the parallel port PNP resources by registering a PNP driver with , but ignores the return value. (The it uses has only the and members filled in.) The driver's Comedi "detach" handler unconditionally unregisters the PNP driver with . It is possible for to return
