ID:10056 - Exploit for Resource exhaustion in Linux kernel - CVE-2017-5972

Link to public exploit:

Vulnerability description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The TCP stack in the Linux kernel 3.x does not properly implement a SYN cookie protection mechanism for the case of a fast network connection, which allows remote attackers to cause a denial of service (CPU consumption) by sending many TCP SYN packets, as demonstrated by an attack against the kernel-3.10.0 package in CentOS Linux 7. NOTE: third parties have been unable to discern any relationship between the GitHub Engineering finding and the Trigemini.c attack code.
