{"id":"CVE-2016-0821","details":"The LIST_POISON feature in include/linux/poison.h in the Linux kernel before 4.3, as used in Android 6.0.1 before 2016-03-01, does not properly consider the relationship to the mmap_min_addr value, which makes it easier for attackers to bypass a poison-pointer protection mechanism by triggering the use of an uninitialized list entry, aka Android internal bug 26186802, a different vulnerability than CVE-2015-3636.","modified":"2026-03-12T22:09:55.443495Z","published":"2016-03-12T21:59:05.900Z","references":[{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2971-2"},{"type":"ADVISORY","url":"http://source.android.com/security/bulletin/2016-03-01.html"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2015/05/02/6"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2967-2"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2968-1"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/84260"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2970-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2971-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2971-3"},{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3607"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2967-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2968-2"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2969-1"},{"type":"FIX","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8a5e5e02fc83aaf67053ab53b359af08c6c49aaf"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/8a5e5e02fc83aaf67053ab53b359af08c6c49aaf"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2016-0821.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"4.3"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0.1"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
