In this\ncase status_resync() will be stuck in the loop to print a large amount\nof '=', which will end up soft lockup.\n\nFix the problem by setting 'resync' to MD_RESYNC_ACTIVE in this case,\nthis way resync in progress will be reported to user.","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-667"],"references":["https://git.kernel.org/stable/c/23309704e90859af2662bedc44101e6d1d2ece7e","https://git.kernel.org/stable/c/6efddf1e32e2a264694766ca485a4f5e04ee82a7","https://git.kernel.org/stable/c/b4acb6c3ede88d6b7d33742a09e63cfce5e7fb69"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2023-53620","score":0.00156,"percentile":0.04677,"date":"2026-11-01"},"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).
