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.</p> <p>Similar commit: commit 0ed554fd769a (&#34;media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()&#34;)</p> <p><strong>Affected:</strong> Linux, Siemens SIMATIC CN 4100</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>media: dvb-frontends: w7090p: fix null-ptr-deref in w7090p_tuner_write_serpar and w7090p_tuner_read_serpar</p> <p>In w7090p_tuner_write_serpar, msg is controlled by user.
