Vulnerability from fkie_nvd - Published: 2025-05-20 16:15 - Updated: 2026-06-17 09:15

Severity

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix error handling path in bnxt_init_chip() WARN_ON() is triggered in __flush_work() if bnxt_init_chip() fails because we call cancel_work_sync() on dim work that has not been initialized. WARNING: CPU: 37 PID: 5223 at kernel/workqueue.c:4201 __flush_work.isra.0+0x212/0x230 The driver relies on the BNXT_STATE_NAPI_DISABLED bit to check if dim work has already been cancelled. But in the bnxt_open() path, BNXT_STATE_NAPI_DISABLED is not set and this causes the error path to think that it needs to cancel the uninitalized dim work. Fix it by setting BNXT_STATE_NAPI_DISABLED during initialization. The bit will be cleared when we enable NAPI and initialize dim work.

But in the bnxt_open() path,\nBNXT_STATE_NAPI_DISABLED is not set and this causes the error\npath to think that it needs to cancel the uninitalized dim work.\nFix it by setting BNXT_STATE_NAPI_DISABLED during initialization.\nThe bit will be cleared when we enable NAPI and initialize dim work."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
