{"id":"CVE-2019-5489","details":"The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server.","modified":"2026-04-02T02:07:42.135536Z","published":"2019-01-07T17:29:00.470Z","related":["SUSE-SU-2019:14089-1","SUSE-SU-2019:1527-1","SUSE-SU-2019:1529-1","SUSE-SU-2019:1530-1","SUSE-SU-2019:1532-1","SUSE-SU-2019:1533-1","SUSE-SU-2019:1534-1","SUSE-SU-2019:1535-1","SUSE-SU-2019:1536-1","SUSE-SU-2019:1550-1","SUSE-SU-2019:1692-1","SUSE-SU-2019:2430-1","openSUSE-SU-2019:1479-1","openSUSE-SU-2019:1579-1"],"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2019/06/msg00011.html"},{"type":"WEB","url":"https://seclists.org/bugtraq/2019/Jun/26"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2019/06/msg00010.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujul2020.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3309"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190307-0001/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4159"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3967"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4057"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4164"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2809"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4058"},{"type":"ADVISORY","url":"https://arxiv.org/abs/1901.01161"},{"type":"ADVISORY","url":"https://www.theregister.co.uk/2019/01/05/boffins_beat_page_cache/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2029"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2043"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4056"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4255"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0204"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4465"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3517"},{"type":"ADVISORY","url":"http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-pagecache-en"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2473"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2808"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106478"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2837"},{"type":"FIX","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=574823bfab82d9d8fa47f422778043fbb4b4f50e"},{"type":"FIX","url":"https://bugzilla.suse.com/show_bug.cgi?id=1120843"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/574823bfab82d9d8fa47f422778043fbb4b4f50e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git","events":[{"introduced":"0"},{"fixed":"574823bfab82d9d8fa47f422778043fbb4b4f50e"}]},{"type":"GIT","repo":"https://github.com/torvalds/linux","events":[{"introduced":"0"},{"fixed":"574823bfab82d9d8fa47f422778043fbb4b4f50e"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git","events":[{"introduced":"0"},{"fixed":"574823bfab82d9d8fa47f422778043fbb4b4f50e"}]},{"type":"GIT","repo":"https://github.com/torvalds/linux","events":[{"introduced":"0"},{"fixed":"574823bfab82d9d8fa47f422778043fbb4b4f50e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-5489.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.19.13"}]},{"events":[{"introduced":"0"},{"last_affected":"4.19.13"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
