Summary

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: fix primary_if leak on failed linearization If the skb has a frag_list, it must be linearized before it can be split using skb_split(). But when this step failed, it must not only free the skb but also take care of the reference to the already found primary_if.
