The below post also mentions a heap overflow. While there is a semantic overflow (17 bytes being copied into a 9-byte buffer), in reality, the object whose member is being overflowed resides in a kernel heap slab cache that includes enough padding that there is no possible corruption. So, it's a bug but not a vulnerability. Reference: http://marc.info/?l=linux-netdev&m=128872251418192&w=2 -Dan
