Jonathan Looney discovered that the TCP retransmission queue implementation
in tcp_fragment in the Linux kernel could be fragmented when handling
certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker
could use this to cause a denial of service. This has been fixed in stable
kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed
in commit f070ef2ac66716357066b683fb0baf55f8191a2e.
