{"id":"CVE-2020-8428","details":"fs/namei.c in the Linux kernel before 5.5 has a may_create_in_sticky use-after-free, which allows local users to cause a denial of service (OOPS) or possibly obtain sensitive information from kernel memory, aka CID-d0cb50185ae9. One attack vector may be an open system call for a UNIX domain socket, if the socket is being moved to a new parent directory and its old parent directory is being removed.","modified":"2026-03-15T22:36:32.756404Z","published":"2020-01-29T00:15:10.953Z","related":["MGASA-2020-0073","MGASA-2020-0089","SUSE-SU-2020:0511-1","SUSE-SU-2020:0558-1","SUSE-SU-2020:0559-1","SUSE-SU-2020:0560-1","SUSE-SU-2020:0580-1","SUSE-SU-2020:0584-1","SUSE-SU-2020:0613-1","SUSE-SU-2020:0649-1","SUSE-SU-2020:0667-1","SUSE-SU-2020:1663-1","openSUSE-SU-2020:0336-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html"},{"type":"WEB","url":"https://usn.ubuntu.com/4318-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4319-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4320-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4324-1/"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2020/02/02/1"},{"type":"WEB","url":"http://packetstormsecurity.com/files/157233/Kernel-Live-Patch-Security-Notice-LSN-0065-1.html"},{"type":"WEB","url":"https://usn.ubuntu.com/4325-1/"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4667"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2020/01/28/4"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20200313-0003/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4698"},{"type":"ADVISORY","url":"https://www.openwall.com/lists/oss-security/2020/01/28/2"},{"type":"FIX","url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d0cb50185ae942b03c4327be322055d622dc79f6"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/d0cb50185ae942b03c4327be322055d622dc79f6"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-8428.json","unresolved_ranges":[{"events":[{"introduced":"4.19"},{"fixed":"5.5"}]}]}}],"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:N/A:H"}]}
