If an error occurs subsequently (eg, ksmbd_iov_pin_rsp fails)\nor a scavenger accesses the file, it leads to a use-after-free when\naccessing fp properties (eg fp->create_time).\n\nMove the single put to the end of the function below err_out2 so fp\nstays valid until smb2_open returns.","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-416"],"references":["https://git.kernel.org/stable/c/1baff47b81f94f9231c91236aa511420d0e266b9","https://git.kernel.org/stable/c/4db3dcac84c2f14a45ae201efb38de1fb1bfc009","https://git.kernel.org/stable/c/97a0cd55283b4e63fd92804da91c8d9896adcad9","https://git.kernel.org/stable/c/ce2e164c1c51c3f7813b80f8c926836e896bcbb3","https://git.kernel.org/stable/c/f0ff7f12398e85b3a11745ff7feab6246f3d75c2"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-53010","score":0.00444,"percentile":0.38666,"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).
