A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the "atalk_sum_skb()" function when creating the checksum of an AppleTalk frame that is shorter than specified in the header. This can be exploited to trigger a "BUG_ON" condition by sending a specially crafted AppleTalk frame to a vulnerable system.
Successful exploitation requires that the AppleTalk kernel module is loaded.
Solution: Update to version 220.127.116.11.
