Updating rd_offset prematurely can lead to the host accessing\nan uninitialized or incomplete element, resulting in data corruption.\n\nInvoke the buffer write before updating rd_offset to ensure the element\nis fully written before signaling its availability.","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-908"],"references":["https://git.kernel.org/stable/c/0007ef098dab48f1ba58364c40b4809f1e21b130","https://git.kernel.org/stable/c/44b9620e82bbec2b9a6ac77f63913636d84f96dc","https://git.kernel.org/stable/c/6f18d174b73d0ceeaa341f46c0986436b3aefc9a","https://git.kernel.org/stable/c/e2176aa3ba4361e98d9f91178a762dca6cf21fe0","https://git.kernel.org/stable/c/f704a80d9fa268e51a6cc5242714502c3c1fa605"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-30T13:47:47.119061695+00:00"},"epss":{"cve":"CVE-2025-38429","score":0.00465,"percentile":0.40295,"date":"2026-10-30"},"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).
