If we fail to\nallocate that clone, proceeding with async decryption can lead to\nvarious issues (UAF on the skb, writing into userspace memory after\nthe recv() call has returned).\n\nIn this case, wait for all pending decryption requests.","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":[],"references":["https://git.kernel.org/stable/c/39dec4ea3daf77f684308576baf483b55ca7f160","https://git.kernel.org/stable/c/4fc109d0ab196bd943b7451276690fb6bb48c2e0","https://git.kernel.org/stable/c/9f83fd0c179e0f458e824e417f9d5ad53443f685","https://git.kernel.org/stable/c/b8a6ff84abbcbbc445463de58704686011edc8e1","https://git.kernel.org/stable/c/c61d4368197d65c4809d9271f3b85325a600586a"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-40176","score":0.00487,"percentile":0.41646,"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).
