Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> can: can327: can327_feed_frame_to_netdev(): fix potential skb leak when netdev is down<br /> <br /> In can327_feed_frame_to_netdev(), it did not free the skb when netdev<br /> is down, and all callers of can327_feed_frame_to_netdev() did not free<br /> allocated skb too. That would trigger skb leak.<br /> <br /> Fix it by adding kfree_skb() in can327_feed_frame_to_netdev() when netdev<br /> is down. Not tested, just compiled.
