CVE-2023-54066

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

media: dvb-usb-v2: gl861: Fix null-ptr-deref in gl861_i2c_master_xfer

In gl861_i2c_master_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach gl861_i2c_master_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.
