Summary
media: dvb-frontends: w7090p: fix null-ptr-deref in w7090p_tuner_write_serpar and w7090p_tuner_read_serpar
Details

In the Linux kernel, the following vulnerability has been resolved:

media: dvb-frontends: w7090p: fix null-ptr-deref in w7090ptunerwriteserpar and w7090ptunerreadserpar

In w7090ptunerwrite_serpar, msg is controlled by user. When msg[0].buf is null and msg[0].len is zero, former checks on msg[0].buf would be passed. If accessing msg[0].buf[2] without sanity check, null pointer deref would happen. We add check on msg[0].len to prevent crash.
