{"id":"CVE-2018-19854","details":"An issue was discovered in the Linux kernel before 4.19.3. crypto_report_one() and related functions in crypto/crypto_user.c (the crypto user configuration API) do not fully initialize structures that are copied to userspace, potentially leaking sensitive memory to user programs. NOTE: this is a CVE-2013-2547 regression but with easier exploitability because the attacker does not need a capability (however, the system must have the CONFIG_CRYPTO_USER kconfig option).","modified":"2026-03-12T22:48:48.714167Z","published":"2018-12-04T16:29:00.587Z","related":["SUSE-SU-2019:0150-1","SUSE-SU-2019:0196-1","SUSE-SU-2019:0222-1","SUSE-SU-2019:0224-1","openSUSE-SU-2019:0065-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3309"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3517"},{"type":"ADVISORY","url":"https://kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.3"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3872-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3878-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3878-2/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3901-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3901-2/"},{"type":"FIX","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f43f39958beb206b53292801e216d9b8a660f087"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/f43f39958beb206b53292801e216d9b8a660f087"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"4.19.3"}]},{"events":[{"introduced":"0"},{"last_affected":"14.04"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.10"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-19854.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
