Description
In the Linux kernel, the following vulnerability has been resolved:
comedi: ni_usb6501: fix NULL-deref in command paths
The driver uses endpoint-sized USB transfer buffers but had no sanity
checks on the sizes. This can lead to zero-size-pointer dereferences or
overflowed transfer buffers in ni6501_port_command() and
ni6501_counter_command() if a (malicious) device has smaller max-packet
sizes than expected (or when doing descriptor fuzz testing).
Add the missing sanity checks to probe().
