It is discouraged to\nunregister the netdev in this path, so the device may still be visible\nto userspace and kernel helpers.\n\nIn gve, shutdown() tears down most internal data structures. If an\nethtool operation is dispatched after shutdown(), it will dereference\nfreed or NULL pointers, leading to a kernel panic. While graceful\nshutdown normally quiesces userspace before invoking the reboot\nsyscall, forced shutdowns (as observed on GCP VMs) can still trigger\nthis path.\n\nFix by calling netif_device_detach() in shutdown().\nThis marks the device as detached so the ethtool ioctl handler\nwill skip dispatching operations to the driver.","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/48a4e89d50e8ea52e800bc7865970b92fcf4647c","https://git.kernel.org/stable/c/75a9a46d67f46d608205888f9b34e315c1786345","https://git.kernel.org/stable/c/9d8a41e9a4ff83ff666de811e7f012167cdc00e9","https://git.kernel.org/stable/c/a7efffeecb881b4649fdc30de020ef910f35d646","https://git.kernel.org/stable/c/ba51d73408edf815cbaeab148625576c2dd90192"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-38735","score":0.0017,"percentile":0.06311,"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).
