{"id":"CVE-2017-8797","details":"The NFSv4 server in the Linux kernel before 4.11.3 does not properly validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or LAYOUTGET operand in a UDP packet from a remote attacker. This type value is uninitialized upon encountering certain error conditions. This value is used as an array index for dereferencing, which leads to an OOPS and eventually a DoS of knfsd and a soft-lockup of the whole system.","modified":"2026-03-12T22:41:14.084646Z","published":"2017-07-02T17:29:00.177Z","related":["SUSE-SU-2017:2043-1","SUSE-SU-2017:2046-1","SUSE-SU-2017:2062-1","SUSE-SU-2017:2063-1","SUSE-SU-2017:2064-1","SUSE-SU-2017:2065-1","SUSE-SU-2017:2066-1","SUSE-SU-2017:2067-1","SUSE-SU-2017:2068-1","SUSE-SU-2017:2070-1"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/99298"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2077"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2437"},{"type":"ADVISORY","url":"http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.11.3"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1038790"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:1842"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2669"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1466329"},{"type":"FIX","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b550a32e60a4941994b437a8d662432a486235a5"},{"type":"FIX","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f961e3f2acae94b727380c0b74e2d3954d0edf79"},{"type":"FIX","url":"http://www.openwall.com/lists/oss-security/2017/06/27/5"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/b550a32e60a4941994b437a8d662432a486235a5"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/f961e3f2acae94b727380c0b74e2d3954d0edf79"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"4.0"},{"fixed":"4.1.40"}]},{"events":[{"introduced":"4.2"},{"fixed":"4.4.70"}]},{"events":[{"introduced":"4.5"},{"fixed":"4.9.30"}]},{"events":[{"introduced":"4.11"},{"fixed":"4.11.3"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-8797.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
