When a new fragment is adjacent to an existing fragment, the code checks whether the new fragment also closes the gap to the next or previous list entry.</p> <p>Those neighbor lookups currently assume that the current fragment always has a real next or previous fragment. At a list edge, the next or previous entry is the list head, not a struct fwnet_fragment_info.</p> <p>The gap checks also compare against the old edge of the current fragment instead of the edge after adding the new fragment. As a result, a fragment that bridges two existing ranges may leave two adjacent ranges unmerged, so fwnet_pd_is_complete() can miss a complete datagram.</p> <p>Check for the list head before looking up the neighboring fragment, and compare the neighbor against the new fragment&#39;s far edge when deciding whether to merge all three ranges.</p> <p>This issue was found by a static analysis checker and confirmed by manual source review.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>firewire: net: Fix fragmented datagram reassembly</p> <p>fwnet_frag_new() keeps a sorted list of received fragments for a partial datagram.
