Disable tx napi before\ndeleting it in mt76_dma_cleanup().\n\n WARNING: CPU: 4 PID: 18828 at net/core/dev.c:7288 __netif_napi_del_locked+0xf0/0x100\n CPU: 4 UID: 0 PID: 18828 Comm: modprobe Not tainted 6.15.0-rc4 #4 PREEMPT(lazy)\n Hardware name: ASUS System Product Name/PRIME X670E-PRO WIFI, BIOS 3035 09/05/2024\n RIP: 0010:__netif_napi_del_locked+0xf0/0x100\n Call Trace:\n <TASK>\n mt76_dma_cleanup+0x54/0x2f0 [mt76]\n mt7921_pci_remove+0xd5/0x190 [mt7921e]\n pci_device_remove+0x47/0xc0\n device_release_driver_internal+0x19e/0x200\n driver_detach+0x48/0x90\n bus_remove_driver+0x6d/0xf0\n pci_unregister_driver+0x2e/0xb0\n __do_sys_delete_module.isra.0+0x197/0x2e0\n do_syscall_64+0x7b/0x160\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nTested with mt7921e but the same pattern can be actually applied to other\nmt76 drivers calling mt76_dma_cleanup() during removal. Tx napi is enabled\nin their *_dma_init() functions and only toggled off and on again inside\ntheir suspend/resume/reset paths. So it should be okay to disable tx\nnapi in such a generic way.\n\nFound by Linux Verification Center (linuxtesting.org).","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":[],"references":["https://git.kernel.org/stable/c/2b81e76db3667d1f7f2ad44e9835cdaf8dea95a8","https://git.kernel.org/stable/c/5e700b06b970fc19e3a1ecb244e14785f3fbb8e3","https://git.kernel.org/stable/c/78ab4be549533432d97ea8989d2f00b508fa68d8","https://git.kernel.org/stable/c/b892e830d1ea8c5475254b98827771f7366f1039","https://git.kernel.org/stable/c/ca5b213bf4b4224335a8131a26805d16503fca5f"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-38009","score":0.00214,"percentile":0.11767,"date":"2026-10-31"},"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).
