Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: sxgbe: fix potential NULL dereference in sxgbe_rx()<br />
<br />
Currently, when skb is null, the driver prints an error and then<br />
dereferences skb on the next line.<br />
<br />
To fix this, let&#39;s add a &#39;break&#39; after the error message to switch<br />
to sxgbe_rx_refill(), which is similar to the approach taken by the<br />
other drivers in this particular case, e.g. calxeda with xgmac_rx().<br />
<br />
Found during a code review.
