This ensures unittest_data is automatically freed when\nit goes out of scope in error paths.\n\nFor the success path, use retain_and_null_ptr() to transfer ownership\nof the memory to the device tree and prevent double freeing.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/235a1eb8d2dcc49a6cf0a5ee1aa85544a5d0054b","https://git.kernel.org/stable/c/4c7ad40c285ab85e3614433e063f14aac2e2fe17","https://git.kernel.org/stable/c/58baf98d1bdab897fd796f39a16061bade229d71","https://git.kernel.org/stable/c/f09b0f705bd7197863b90256ef533a6414d1db2c"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-23137","score":0.00176,"percentile":0.07053,"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).
