In the Linux kernel, the following vulnerability has been resolved:
batman-adv: frag: free unfragmentable packet
The caller of batadv_frag_send_packet() assume that the skb provided to the function are always consumed. But the pre-check for an empty payload or the zero fragment size returned an error without any further actions.
A failed pre-check must use the same error handling code as the rest of the function.
