### [CVE-2017-13686](https://www.cve.org/CVERecord?id=CVE-2017-13686) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=brightgreen) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brightgreen) ### Description net/ipv4/route.c in the Linux kernel 4.13-rc1 through 4.13-rc6 is too late to check for a NULL fi field when RTM_F_FIB_MATCH is set, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via crafted system calls.
