This is because dev->buf was\nfreed but never set to NULL and is again freed in amd_pmf_remove().\n\nTo avoid subtle allocation bugs in failures leading to a double free\nchange all allocations into device managed allocations.","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-415"],"references":["https://git.kernel.org/stable/c/0d10b532f861253c283863522d59d099fcb0796d","https://git.kernel.org/stable/c/d6a38e1a82d2f9abd0bae84a354654bccb8389f6","https://git.kernel.org/stable/c/d9db3a941270d92bbd1a6a6b54a10324484f2f2d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2025-38421","score":0.00219,"percentile":0.12255,"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).
