This is because the conversion is\ndone after the multiplication. So arithmetic overflow and thus in\nincorrect value is possible.\n\nCorrect an instance of this in the inter packet delay calculation.  Fix by\nensuring one of the operands is u64 which will promote the other to u64 as\nwell ensuring no overflow.","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":["CWE-190"],"references":["https://git.kernel.org/stable/c/06039d8afefdbac05bcea5f397188407eba2996d","https://git.kernel.org/stable/c/252f4afd4557a2e7075f793a5c80fe6dd9e9ee4a","https://git.kernel.org/stable/c/31dca00d0cc9f4133320d72eb7e3720badc6d6e6","https://git.kernel.org/stable/c/3f09ec80f115d2875d747ed28adc1773037e0f8b","https://git.kernel.org/stable/c/79c164e61f818054cd6012e9035701840d895c51"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49404","score":0.00276,"percentile":0.20025,"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).
