Details
In the Linux kernel, the following vulnerability has been resolved:
media: az6007: Fix null-ptr-deref in az6007_i2c_xfer()
In az6007_i2c_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 az6007_i2c_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.
