CVE-2023-54111: pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups

In the Linux kernel, the following vulnerability has been resolved: pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups of_find_node_by_phandle() returns a node pointer with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing of_node_put() to avoid refcount leak.

Security readout for executives and security teams

Plain-English summary

This CVE covers a Linux kernel reference-count leak in the Rockchip pinctrl driver. The public record does not provide a CVSS score, CWE, or concrete attack impact. Treat it as a kernel maintenance issue for Rockchip-based systems, especially embedded or appliance fleets, and prioritize normal kernel updates through trusted vendor channels.

Executive priority

Low operational urgency unless you manage Rockchip-based appliances or embedded Linux fleets. No exploitation evidence is provided, but kernel refcount leaks should still be closed during routine patch cycles because embedded devices often lag behind upstream fixes.

Technical view

rockchip_pinctrl_parse_groups calls of_find_node_by_phandle, which increments a device-tree node reference count. The fix adds the missing of_node_put when the node is no longer needed. The source describes a refcount leak only; it does not establish privilege escalation, code execution, or a specific denial-of-service path.

Likely exposure

Exposure appears limited to Linux systems using affected kernel versions with the Rockchip pinctrl driver path. This is most relevant to Rockchip SoC devices, embedded Linux systems, and vendor kernels derived from the listed upstream stable ranges.

Exploitation context

The bundle marks KEV as false and provides no cited evidence of active exploitation or public exploit use. The described weakness is an internal kernel refcount leak during pinctrl group parsing, but the sources do not describe attacker control or trigger conditions.

Researcher notes

The record lacks CVSS, CWE, and exploitability analysis. Research should focus on whether untrusted device-tree data or repeated parsing paths can make the refcount leak security-relevant in real deployments. Avoid assuming impact beyond the source-described leak.

Mitigation direction

  • Update affected Linux kernels through distribution or device-vendor channels.
  • Confirm the vendor kernel includes the referenced upstream stable fix.
  • Prioritize Rockchip-based production devices and long-lived embedded images.
  • Monitor CVE and kernel stable guidance for revised severity or impact details.

Validation and detection

  • Inventory systems running Linux on Rockchip SoCs or vendor kernels.
  • Map deployed kernel versions against the affected version list.
  • Check kernel package changelogs for the referenced stable commits.
  • Confirm no unsupported custom kernel omits the of_node_put fix.
