{"id":"CVE-2019-19046","details":"A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time","modified":"2026-03-12T23:08:20.107347Z","published":"2019-11-18T06:15:11.437Z","related":["ALSA-2020:4431","SUSE-SU-2019:3200-1","SUSE-SU-2019:3317-1","SUSE-SU-2019:3372-1","SUSE-SU-2020:0093-1","SUSE-SU-2020:0613-1","openSUSE-SU-2019:2675-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/O3PSDE6PTOTVBK2YTKB2TFQP2SUBVSNF/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PY7LJMSPAGRIKABJPDKQDTXYW3L5RX2T/"},{"type":"WEB","url":"https://usn.ubuntu.com/4302-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4319-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/4325-1/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html"},{"type":"REPORT","url":"https://bugzilla.suse.com/show_bug.cgi?id=1157304"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/4aa7afb0ee20a97fbf0c5bab3df028d5fb85fdab"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-19046.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"5.3.11"}]},{"events":[{"introduced":"0"},{"last_affected":"30"}]},{"events":[{"introduced":"0"},{"last_affected":"31"}]},{"events":[{"introduced":"0"},{"last_affected":"15.1"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
