Summary
In the Linux kernel, the following vulnerability has been resolved: pcmcia: Fix a NULL pointer dereference in __iodyn_find_io_region() In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to res and used in pci_bus_alloc_resource(). There is a dereference of res in pci_bus_alloc_resource(), which could lead to a NULL pointer dereference on failure of pcmcia_make_resource(). Fix this bug by adding a check of res.
