CVE-2026-72230

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.
