grant table operations mishandle reference counts

ISSUE DESCRIPTION We have discovered a number of bugs in the code mapping and unmapping grant references. If a grant is mapped with both the GNTMAPdevicemap and GNTMAPhostmap flags, but unmapped only with hostmap, the devicemap portion remains but the page reference counts are lowered as though i...

CVE-2017-7487

The ipxitfioctl function in net/ipx/afipx.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...

Software defense: safe unlinking and reference count hardening

Object lifetime management vulnerabilities represent a very common class of memory safety vulnerability. These vulnerabilities come in many shapes and sizes, and are typically quite difficult to mitigate generically. Vulnerabilities of this type result commonly from incorrect accounting with...
