Such implementation potentially could result\nin a use after free of the request pointer when percpu_ref_put() is\ncalled in nvmet_req_complete().\n\nAvoid such problem by using a local variable to save the sq pointer\nbefore calling __nvmet_req_complete(), thus avoiding dereferencing the\nreq pointer after that function call.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/04c394208831d5e0d5cfee46722eb0f033cd4083","https://git.kernel.org/stable/c/6173a77b7e9d3e202bdb9897b23f2a8afe7bf286","https://git.kernel.org/stable/c/8ed9813871038b25a934b21ab76b5b7dbf44fc3a","https://git.kernel.org/stable/c/a6317235da8aa7cb97529ebc8121cc2a4c4c437a","https://git.kernel.org/stable/c/bcd535f07c58342302a2cd2bdd8894fe0872c8a9"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2023-53116","score":0.00538,"percentile":0.45014,"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).
