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

media: dvb-frontends: dib7090p: fix null-ptr-deref in dib7090p_rw_on_apb()

In dib7090p_rw_on_apb, 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. Similar issue occurs when access
msg[1].buf[0] and msg[1].buf[1].
