CVE-2017-7487
Last modified
CVE-2017-7487 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
