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...

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...

UBUNTU-CVE-2019-11478

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...
