The\nempty-iterator check can do the same.\n\nFor synchronous writes, netfs_unbuffered_write_iter_locked() may then\nreturn an unrelated error instead of wreq->error. This is reachable\nthrough CIFS if cifs_prepare_write() fails to reopen the file or obtain\ncredits.\n\nInitialize ret to 0 so the caller returns wreq->error if no data was\nwritten, or the number of bytes already written otherwise.\n\nFound with Clang's -Wconditional-uninitialized.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2e38d500471d097cda87d7d374bbc1b13493075d","https://git.kernel.org/stable/c/3d038eebdbd400c3bc4b66bd8aa0dff0c2bcce26","https://git.kernel.org/stable/c/f18e8774f4d3137fa0a5fb8ffa83d59a719666d8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97610","score":0.00198,"percentile":0.09478,"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).
