Consequently, if a\nmapping, like fuse, traditionally does not have data integrity semantics,\nthere is no need to wait at all; we can simply skip these inodes.\n\nThis restores fuse back to prior behavior where syncs are no-ops.  This\nfixes a user regression where if a system is running a faulty fuse server\nthat does not reply to issued write requests, this causes wait_sb_inodes()\nto wait forever.","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-835"],"references":["https://git.kernel.org/stable/c/3f4ed5e2b8f111553562507ad6202432c7c57731","https://git.kernel.org/stable/c/f9a49aa302a05e91ca01f69031cb79a0ea33031f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-23109","score":0.00133,"percentile":0.02834,"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).
