Fix this everywhere\nby forcing 64-bit multiplication. Extract this formula into separate\nsmall helper and use it consistently in various places.\n\nSpeculative-preventing formula utilizing index_mask trick is left as is,\nbut explicit u64 casts are added in both places.","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/063e092534d4c6785228e5b1eb6e9329f66ccbe4","https://git.kernel.org/stable/c/3c7256b880b3a5aa1895fd169a34aa4224a11862","https://git.kernel.org/stable/c/87ac0d600943994444e24382a87aa19acc4cd3d4"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2022-50167","score":0.00263,"percentile":0.17947,"date":"2026-10-25"},"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).
