CVE-2022-49028: ixgbevf: Fix resource leak in ixgbevf_init_module()

In the Linux kernel, the following vulnerability has been resolved: ixgbevf: Fix resource leak in ixgbevf_init_module() ixgbevf_init_module() won't destroy the workqueue created by create_singlethread_workqueue() when pci_register_driver() failed. Add destroy_workqueue() in fail path to prevent the resource leak. Similar to the handling of u132_hcd_init in commit f276e002793c ("usb: u132-hcd: fix resource leak")

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue is a resource leak in the ixgbevf network driver when driver registration fails during module initialization. It is not described as data theft, privilege escalation, or remote code execution in the provided sources.

Executive priority

Handle through routine kernel patch management unless vendor guidance raises severity. There is no provided evidence of active exploitation or severe impact, but kernel hygiene remains important for fleet reliability.

Technical view

ixgbevf_init_module() creates a single-thread workqueue but, on pci_register_driver() failure, previously did not destroy it. The kernel fix adds destroy_workqueue() on the failure path to prevent the leaked resource.

Likely exposure

Exposure is limited to Linux systems running affected kernel builds with the ixgbevf driver code present. The provided data does not identify distributions, packages, or exact deployed product versions.

Exploitation context

The source bundle does not report active exploitation, public exploit activity, KEV listing, CVSS, or a CWE. The issue appears tied to an error path during driver initialization, not normal packet processing.

Researcher notes

The record lacks CVSS, CWE, exploit evidence, and distribution mapping. Analysis should focus on whether local kernel builds include the ixgbevf init failure-path fix and how vendors backported it.

Mitigation direction

  • Check your Linux distribution kernel advisories for CVE-2022-49028 coverage.
  • Update to a kernel containing the referenced stable fixes when available.
  • Prioritize hosts using Intel ixgbevf virtual function networking.
  • Track vendor backports rather than relying only on upstream version numbers.

Validation and detection

  • Inventory Linux kernel versions across affected infrastructure.
  • Identify systems loading or packaging the ixgbevf driver.
  • Confirm vendor advisory status for CVE-2022-49028.
  • Verify deployed kernels include one of the referenced upstream fixes.
