This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service.","modified":"2026-04-16T01:44:15.972507899Z","published":"2017-12-27T17:08:20.437Z","related":["SUSE-SU-2018:0383-1","SUSE-SU-2018:0416-1","SUSE-SU-2018:0482-1","SUSE-SU-2018:0986-1","SUSE-SU-2021:3935-1","openSUSE-SU-2024:10728-1","openSUSE-SU-2024:13704-1"],"references":[{"type":"WEB","url":"https://usn.ubuntu.com/3619-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/3619-2/"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/102325"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1040057"},{"type":"ADVISORY","url":"https://anonscm.debian.org/cgit/kernel/linux.git/tree/debian/patches/bugfix/all/bpf-fix-branch-pruning-logic.patch?h=stretch-security"},{"type":"ADVISORY","url":"https://github.com/torvalds/linux/commit/c131187db2d3fa2f8bf32fdf4e9a4ef805168467"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/usn/usn-3523-2/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2017/dsa-4073"},{"type":"ADVISORY","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c131187db2d3fa2f8bf32fdf4e9a4ef805168467"},{"type":"FIX","url":"https://www.spinics.net/lists/stable/msg206984.html"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-17862.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.14.8"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
