SUSE CVE-2019-11477

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,...

TCP SACK Panic - Linux Kernel Vulnerability

Jonathan Looney discovered that the TCP retransmission queue implementation in tcpfragment 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...

Kernel: tcp: integer overflow while processing SACK blocks allows remote denial of service

An integer overflow 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. Each fragment is about TCP maximum segment size MSS...
