{"id":"CVE-2018-14619","details":"A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The \"null skcipher\" was being dropped when each af_alg_ctx was freed instead of when the aead_tfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user being able to crash the system or possibly escalate privileges.","modified":"2026-03-15T22:19:06.509095Z","published":"2018-08-30T12:29:01.407Z","references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/105200"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:2948"},{"type":"ADVISORY","url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2018-0013"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14619"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b32a7dc8aef1882fbf983eb354837488cc9d54dc"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"4.14"},{"fixed":"4.14.8"}]},{"events":[{"introduced":"0"},{"last_affected":"4.15-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"4.15-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"4.15-rc3"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-14619.json"}}],"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:H/A:H"}]}
