An online resize to a size that is not\nintegral to cluster size results in the last iteration attempting to\ngrow the fs by a negative amount, which trips a BUG_ON and leaves the fs\nwith a corrupted in-memory superblock.","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-1284"],"references":["https://git.kernel.org/stable/c/0082e99a9074ff88eff729c70c93454c8588d8e1","https://git.kernel.org/stable/c/69cb8e9d8cd97cdf5e293b26d70a9dee3e35e6bd","https://git.kernel.org/stable/c/72b850a2a996f72541172e7cf686d54a2b29bcd8","https://git.kernel.org/stable/c/7bdfb01fc5f6b3696728aeb527c50386e0ee09a1","https://git.kernel.org/stable/c/80288883294c5b4ed18bae0d8bd9c4a12f297074"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2022-50020","score":0.00208,"percentile":0.11003,"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).
