If off->val.tv_nsec\ncontains invalid values (negative or >= NSEC_PER_SEC), it could lead to\nincorrect calculations or unexpected behavior.\n\nAdd validation to ensure tv_nsec is within the valid range before\nperforming the addition.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06aba58e58492d2b8eae059274caed29025ea96e","https://git.kernel.org/stable/c/1f0c3c0c36c7aedf55a60d9c71c4bd258b8937ce","https://git.kernel.org/stable/c/5b8a40de738b7c4896c2edbc6262bd1b3462ded0","https://git.kernel.org/stable/c/b20d7085ab314672447322c10cc5d1ba443e3b8e","https://git.kernel.org/stable/c/db667d2970c756cc7b483f45f272440f845a665b"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-93146","score":0.00209,"percentile":0.10926,"date":"2026-10-26"},"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).
