CVE-2022-48965: gpio/rockchip: fix refcount leak in rockchip_gpiolib_register()

In the Linux kernel, the following vulnerability has been resolved: gpio/rockchip: fix refcount leak in rockchip_gpiolib_register() The node returned by of_get_parent() with refcount incremented, of_node_put() needs be called when finish using it. So add it in the end of of_pinctrl_get().

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue is a resource accounting bug in the Rockchip GPIO path. A device-tree parent node reference was not released after use, causing a reference count leak. The public record does not provide CVSS, CWE, confirmed exploitation, or impact details beyond the kernel fix description.

Executive priority

Track and remediate through normal kernel maintenance unless Rockchip-based systems are business-critical. The urgency is unclear because severity, impact, and exploitation evidence are not provided in the supplied sources.

Technical view

The fix adds the missing of_node_put() after of_get_parent() in rockchip_gpiolib_register()/of_pinctrl_get() flow. The issue is a reference count leak in Linux kernel Rockchip GPIO handling. The bundle lists Linux kernel affected version ranges and three upstream stable commits.

Likely exposure

Exposure appears limited to Linux kernels using the Rockchip GPIO driver path. The supplied data lists affected Linux kernel versions and commit ranges, but does not identify distributions, devices, or complete downstream package status.

Exploitation context

The CVE is not marked KEV, and the provided sources do not cite active exploitation, public exploit code, or a practical attack path. Treat exploitation status as unconfirmed from this bundle.

Researcher notes

The record is sparse: no CVSS, CWE, or exploit context is included. Analysis should focus on commit inclusion, affected stable branches, and whether the Rockchip GPIO code is reachable on target kernels.

Mitigation direction

  • Review vendor or distribution advisories for kernel packages containing the referenced stable fixes.
  • Update affected Linux kernels to a fixed vendor-supported release where available.
  • Prioritize systems using Rockchip SoCs or Rockchip GPIO functionality for verification.
  • If no vendor package exists, track the listed upstream stable commits for backport status.

Validation and detection

  • Inventory Linux kernel versions on systems with Rockchip hardware or drivers.
  • Check whether the running kernel includes one of the referenced stable commits.
  • Confirm downstream vendor advisories map this CVE to installed kernel packages.
  • Review kernel configuration or device inventory for Rockchip GPIO usage.
