A volume without this set is then seen as not needing\nrecovery and it does not run one, so whatever went wrong is never repaired.\n\nThis change skips resetting the dirty bit when there are volume errors.\n\nReproduced on a volume whose $MFTMirr does not match $MFT, which sets the\nerror flag while leaving the mount read-write: after a write and a sync,\nthe on-disk volume flags read 0x0000 with this driver and 0x0001 with the\nguard in place.","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":[],"references":["https://git.kernel.org/stable/c/0e4c839905418d55bafe571a92533a1d1ac7b0a8","https://git.kernel.org/stable/c/ca1f9933eff777a604eb664d0f9ae433b8664cbf"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-98138","score":0.001,"percentile":0.0084,"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).
