The host is installed with FNET through 4.6.4 and is prone to an out-of-bounds read vulnerability. A flaw is present in the application, which fails to check non empty holes between the IPv6 fragment reassembly. Successful exploitation allows attackers to lead to an uninitialized pointer dereference in _fnet_ip6_reassembly in fnet_ip6.c, and causes denial-of-service.
