CVE-2017-13686
Last modified
CVE-2017-13686 is a vulnerability of currently unknown severity. 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. NOTE: this does not affect any stable release.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
