Then, in\ngfs2_logd(), take sdp->sd_log_flush_lock before calling the above mentioned log\nflushing functions and __gfs2_log_flush().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-667","CWE-362"],"references":["https://git.kernel.org/stable/c/3b28eb75afe520972bacc833850c2b30aa0824cd","https://git.kernel.org/stable/c/49d9be0722da3a4a893ba905720cba1921834ec3","https://git.kernel.org/stable/c/98e8bf249c790d56de1abc4a5f8bd68035a00921","https://git.kernel.org/stable/c/bf5fcd9c37c2546beaf7b401d31aefd89017dc3d","https://git.kernel.org/stable/c/ca95342cb1b39062a03c115830286f0a426053d5"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-53049","score":0.00388,"percentile":0.32617,"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).
