{"id":"CVE-2017-14316","details":"A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node \u003e= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array.","modified":"2026-03-12T22:35:21.048754Z","published":"2017-09-12T15:29:00.237Z","related":["SUSE-SU-2017:2420-1","SUSE-SU-2017:2450-1","SUSE-SU-2017:2466-1","SUSE-SU-2017:2519-1","SUSE-SU-2017:2541-1","SUSE-SU-2017:2611-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/10/msg00009.html"},{"type":"WEB","url":"https://support.citrix.com/article/CTX227185"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/100818"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1039348"},{"type":"ADVISORY","url":"https://www.debian.org/security/2017/dsa-4050"},{"type":"FIX","url":"http://xenbits.xen.org/xsa/advisory-231.html"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.9.0"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-14316.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
