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.
