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).","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":4.7},"cwes":["CWE-200"],"references":["http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f43f39958beb206b53292801e216d9b8a660f087","https://access.redhat.com/errata/RHSA-2019:3309","https://access.redhat.com/errata/RHSA-2019:3517","https://github.com/torvalds/linux/commit/f43f39958beb206b53292801e216d9b8a660f087","https://kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.3"],"products":["canonical:ubuntu_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T20:53:59.789560037+00:00"},"epss":{"cve":"CVE-2018-19854","score":0.0045,"percentile":0.39149,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
