CVE-2022-50120: remoteproc: imx_rproc: Fix refcount leak in imx_rproc_addr_init

In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Fix refcount leak in imx_rproc_addr_init of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not needed anymore. This function has two paths missing of_node_put().

Security readout for executives and security teams

Plain-English summary

This CVE is a Linux kernel resource-management bug in the i.MX remote processor driver. The public record describes a missing reference release, not a confirmed remote compromise path. Business urgency depends on whether your devices run affected Linux kernels with this driver in use.

Executive priority

Handle as routine kernel maintenance unless your environment relies heavily on i.MX remote processor functionality. Escalate only if vendor guidance later confirms meaningful denial-of-service or security impact.

Technical view

The issue is in remoteproc imx_rproc_addr_init. of_parse_phandle() increments a device-tree node reference count, and two error or exit paths failed to call of_node_put(), causing a refcount leak. Kernel stable commits are referenced as the resolution.

Likely exposure

Likely limited to Linux systems whose kernel includes and uses the imx_rproc remoteproc driver, typically i.MX-based embedded or edge devices. The source bundle does not identify specific distributions, appliances, or cloud platforms.

Exploitation context

The supplied sources do not report active exploitation, public exploit availability, KEV listing, CVSS score, or a demonstrated privilege impact. Treat exploitability as unproven from the provided evidence.

Researcher notes

Evidence is narrow: the CVE text describes a missing of_node_put() after of_parse_phandle(). No CVSS, CWE, exploit status, or operational impact is provided. Analysis should avoid assuming remote reachability or privilege escalation.

Mitigation direction

  • Check Linux distribution or device vendor guidance for CVE-2022-50120.
  • Update to a kernel containing the referenced stable commits when available.
  • Prioritize i.MX-based devices using remoteproc or imx_rproc support.
  • Track vendor advisories if kernels are maintained by an OEM or BSP provider.

Validation and detection

  • Inventory Linux kernel versions across embedded and edge fleets.
  • Confirm whether imx_rproc support is built, loaded, or used.
  • Compare kernel source or package changelogs against referenced stable commits.
  • Document systems where vendor fix status remains unknown.
