In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb-v2: af9035: Fix null-ptr-deref in af9035_i2c_master_xfer
In af9035_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 af9035_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.
