NOTE: the vendor states \"there is no kernel bug here.","modified":"2026-04-10T03:46:33.389329Z","published":"2016-02-08T03:59:05Z","related":["SUSE-SU-2016:0785-1","SUSE-SU-2016:1019-1","SUSE-SU-2016:1031-1","SUSE-SU-2016:1032-1","SUSE-SU-2016:1033-1","SUSE-SU-2016:1034-1","SUSE-SU-2016:1035-1","SUSE-SU-2016:1037-1","SUSE-SU-2016:1038-1","SUSE-SU-2016:1039-1","SUSE-SU-2016:1040-1","SUSE-SU-2016:1041-1","SUSE-SU-2016:1045-1","SUSE-SU-2016:1046-1","SUSE-SU-2016:1764-1","SUSE-SU-2017:0575-1"],"database_specific":{"isDisputed":true},"references":[{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3434"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1295287"},{"type":"WEB","url":"http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176484.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00025.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00026.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00027.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00028.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00029.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00030.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00031.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00032.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00033.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00034.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00036.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00037.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html"},{"type":"WEB","url":"http://marc.info/?l=linux-kernel&m=145204362722256&w=2"},{"type":"WEB","url":"http://marc.info/?l=linux-kernel&m=145204641422813&w=2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2015/12/17/12"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2015/12/31/5"},{"type":"WEB","url":"http://www.securityfocus.com/bid/79899"},{"type":"WEB","url":"http://www.securitytracker.com/id/1034899"},{"type":"WEB","url":"https://lkml.org/lkml/2015/12/25/71"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
