It can then be reconstructed at need\nprovided no more than 68 years has elapsed since the last transmission.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/49b8ef1abfe7713e15d9128006cb76e413b12b57","https://git.kernel.org/stable/c/5d5fe8bcd331f1e34e0943ec7c18432edfcf0e8b","https://git.kernel.org/stable/c/a426f29ac3fa3465093567ab763ada46762fb57c","https://git.kernel.org/stable/c/c08cf314191cd0f8699089715efb9eff030f0086","https://git.kernel.org/stable/c/f8cf1368e0a5491b27189a695c36f64e48f3d19d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-30T13:47:47.119061695+00:00"},"epss":{"cve":"CVE-2026-23118","score":0.00098,"percentile":0.00764,"date":"2026-10-30"},"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).
