CVE-2019-11477: Integer Overflow or Wraparound

Jonathan Looney discovered that the TCPSKBCBskb-tcpgsosegs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments SACKs. 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,...

Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB data structure becomes fragmented, which leads to increased resource...
