{"id":"CVE-2017-1000111","details":"Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.","modified":"2026-03-15T21:52:12.909962Z","published":"2017-10-05T01:29:04.430Z","related":["SUSE-SU-2017:2131-1","SUSE-SU-2017:2142-1","SUSE-SU-2017:2150-1","SUSE-SU-2017:2286-1","SUSE-SU-2017:2956-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2931"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3200"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/cve-2017-1000111"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3981"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/100267"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1039132"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2918"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2930"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"2.6.27"},{"fixed":"3.2.92"}]},{"events":[{"introduced":"3.3"},{"fixed":"3.10.108"}]},{"events":[{"introduced":"3.11"},{"fixed":"3.16.47"}]},{"events":[{"introduced":"3.17"},{"fixed":"3.18.65"}]},{"events":[{"introduced":"3.19"},{"fixed":"4.1.44"}]},{"events":[{"introduced":"4.2"},{"fixed":"4.4.82"}]},{"events":[{"introduced":"4.5"},{"fixed":"4.9.43"}]},{"events":[{"introduced":"4.10"},{"fixed":"4.12.7"}]},{"events":[{"introduced":"0"},{"last_affected":"5.0"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.4"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.4"}]},{"events":[{"introduced":"0"},{"last_affected":"7.5"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.4"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-1000111.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
