Instead just return BLK_STS_OK as\nthe repair function has to continue to process the rest of the pages,\nand the endio for the repair bio will do the appropriate cleanup for the\npage that it was given.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/7170875083254b51fcc5d67f96640977083f481e","https://git.kernel.org/stable/c/8cbc3001a3264d998d6b6db3e23f935c158abd4d","https://git.kernel.org/stable/c/d1cb11fb45ebbb1e7dfe5e9038b32ea72c184b14","https://git.kernel.org/stable/c/e76c78c48902dae6fa612749f59162bca0a79e0b","https://git.kernel.org/stable/c/e7e1d15d2bd8c373cf621614ddd17971a2132713"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49168","score":0.00328,"percentile":0.26003,"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).
