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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-20","CWE-416"],"references":["http://www.securityfocus.com/bid/105200","https://access.redhat.com/errata/RHSA-2018:2948","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14619","https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b32a7dc8aef1882fbf983eb354837488cc9d54dc","https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2018-0013"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T20:53:14.491561039+00:00"},"epss":{"cve":"CVE-2018-14619","score":0.00426,"percentile":0.36909,"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).
