Doc Text:
A NULL pointer dereference vulnerability was found in FRRouting within the show_opaque_info_detail function within ospf_opaque.c. When the OSPF daemon (ospfd) is configured with the debug command debug ospf packet all send/recv detail, it attempts to display detailed information of all received or sent OSPF packets through the VTY interface or zlog. Due to a missing check for functab->show_opaque_info, a NULL pointer dereference can occur when processing a crafted LS Update packet.
