CVE-2017-7487

Published: 14 May 2017

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.

From the Ubuntu security team

A reference count bug was discovered in the Linux kernel ipx protocol stack. A local attacker could exploit this flaw to cause a denial of service or possibly other unspecified problems.

Priority

Medium
