This can be reproduced e.g. by running:\n\n    kcapi-rng -b 67 >/dev/null\n\nThere are many ways to fix this without adding back the 'break', but\nthey all seem more awkward than simply adding it back, so do just that.\n\nTested on a machine with Qualcomm Amberwing processor.","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-835"],"references":["https://git.kernel.org/stable/c/05d4d17475d8d094c519bb51658bc47899c175e3","https://git.kernel.org/stable/c/16287397ec5c08aa58db6acf7dbc55470d78087d","https://git.kernel.org/stable/c/233a3cc60e7a8fe0be8cf9934ae7b67ba25a866c","https://git.kernel.org/stable/c/71a89789552b7faf3ef27969b9bc783fa0df3550","https://git.kernel.org/stable/c/8a06f25f5941c145773204f2f7abef95b4ffb8ce"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:46:54.846886191+00:00"},"epss":{"cve":"CVE-2022-48630","score":0.00228,"percentile":0.13594,"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).
