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

    media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()

    In dw2102_i2c_transfer, 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 dw2102_i2c_transfer. If accessing
    msg[i].buf[0] without sanity check, null ptr deref would happen.
    We add check on msg[i].len to prevent crash.
