CVE-2024-58063: wifi: rtlwifi: fix memory leaks and invalid access at probe error path

In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: fix memory leaks and invalid access at probe error path Deinitialize at reverse order when probe fails. When init_sw_vars fails, rtl_deinit_core should not be called, specially now that it destroys the rtl_wq workqueue. And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be leaked. Remove pci_set_drvdata call as it will already be cleaned up by the core driver code and could lead to memory leaks too. cf. commit 8d450935ae7f ("wireless: rtlwifi: remove unnecessary pci_set_drvdata()") and commit 3d86b93064c7 ("rtlwifi: Fix PCI probe error path orphaned memory").

Security readout for executives and security teams

Plain-English summary

CVE-2024-58063 is a Linux kernel availability bug in the Realtek rtlwifi driver. If driver probing fails, cleanup can occur in the wrong order, causing memory leaks or invalid access. The documented impact is local denial of service, not data theft or remote compromise.

Executive priority

Schedule remediation through normal kernel patch cycles, with faster handling for exposed endpoints or appliances using Realtek wireless. This is not currently evidenced as remotely exploitable or actively exploited, but it can affect system availability.

Technical view

The issue is in the rtlwifi PCI probe error path. On init_sw_vars failure, rtl_deinit_core could be called incorrectly, and rtl_pci_deinit/deinit_sw_vars cleanup could be missed. The CVE maps to CWE-401 with CVSS 5.5, AV:L/PR:L/UI:N, affecting availability only.

Likely exposure

Exposure is most likely on Linux systems that include and can load the rtlwifi driver for Realtek wireless hardware. Server exposure is usually limited unless such hardware or modules are present. Downstream advisories from Debian LTS and Siemens indicate distribution or product tracking may matter.

Exploitation context

The source bundle does not identify active exploitation, public exploit code, or KEV listing. The CVSS vector requires local access with low privileges and no user interaction. Treat this as a local availability risk unless vendor advisories provide stronger evidence.

Researcher notes

The strongest evidence is the kernel commit narrative: failed probe cleanup order caused leaks and invalid access. Version range details in the bundle are incomplete for precise fleet matching, so validate against vendor kernel packages and stable branch fix commits.

Mitigation direction

  • Update affected Linux kernels using vendor-supported packages or stable kernel fixes.
  • Prioritize laptops, workstations, appliances, or embedded systems using Realtek rtlwifi hardware.
  • Review Debian LTS or Siemens guidance where those distributions or products are deployed.
  • If patching is delayed, evaluate whether the rtlwifi driver is needed on affected systems.

Validation and detection

  • Inventory kernel versions and compare them with vendor CVE guidance.
  • Check whether rtlwifi modules or Realtek wireless PCI hardware are present.
  • Review package advisories from the operating system or product vendor.
  • Confirm updated kernels include the referenced stable fix commits.
