Padding in structures may be filled with\nrandom (possibly sensitve) data and should never be given directly\nto user-space.\n\nThis patch fixes the copying of xfrm algorithms and the encap\ntemplate in xfrm_user so that padding is zeroed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/0725daaa9a879388ed312110f62dbd5ea2d75f8f","https://git.kernel.org/stable/c/1a351e26cc010d6991fbbd5701ac16581372e26f","https://git.kernel.org/stable/c/5218af4ad5d8948faac19f71583bcd786c3852df","https://git.kernel.org/stable/c/8222d5910dae08213b6d9d4bc9a7f8502855e624"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-28T20:25:46.008810417+00:00"},"epss":{"cve":"CVE-2023-53684","score":0.00148,"percentile":0.03978,"date":"2026-10-28"},"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).
