Failing to check for NULL\nmay lead to a NULL pointer dereference if the result is used later in\nprocessing, potentially causing crashes, data corruption, or undefined\nbehavior.\n\nOn XDP redirect failure, the associated page must be released explicitly\nif it was previously retained via get_page(). Failing to do so may result\nin a memory leak, as the pages reference count is not decremented.","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-476"],"references":["https://git.kernel.org/stable/c/5b83d30c63f9964acb1bc63eb8e670b9e0d2c240","https://git.kernel.org/stable/c/cc3628dcd851ddd8d418bf0c897024b4621ddc92","https://git.kernel.org/stable/c/cefd8a2e2de46209ce66e6d30c237eb59b6c5bfa","https://git.kernel.org/stable/c/d6a9c4e6f9b3ec3ad98468c950ad214af8a2efb9","https://git.kernel.org/stable/c/eefccd889df3b49d92e7349d94c4aa7e1ba19f6c"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2025-37820","score":0.00395,"percentile":0.33463,"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).
