However,\nfor the condition of the file being installed in the fixed file table as\nwell as having O_CLOEXEC flag set, the function returns early. At that\npoint, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,\nthe memory for the newly allocated struct filename is not cleaned up,\ncausing a memory leak.\n\nFix this by setting the REQ_F_NEED_CLEANUP for the request just after the\nsuccessful getname() call, so that when the request is torn down, the\nfilename will be cleaned up, along with other resources needing cleanup.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/18b99fa603d0df5e1c898699c17d3b92ddc80746","https://git.kernel.org/stable/c/2420ef01b2e836fbc05a0a8c73a1016504eb0458","https://git.kernel.org/stable/c/7fbfb85b05bc960cc50e09d03e5e562131e48d45","https://git.kernel.org/stable/c/8f44c4a550570cd5903625133f938c6b51310c9b","https://git.kernel.org/stable/c/b14fad555302a2104948feaff70503b64c80ac01"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-68814","score":0.00216,"percentile":0.11914,"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).
