CVE-2022-50113: ASoc: audio-graph-card2: Fix refcount leak bug in __graph_get_type()

In the Linux kernel, the following vulnerability has been resolved: ASoc: audio-graph-card2: Fix refcount leak bug in __graph_get_type() We should call of_node_put() for the reference before its replacement as it returned by of_get_parent() which has increased the refcount. Besides, we should also call of_node_put() before return.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50113 is a Linux kernel bug in an audio device-tree component. The public record says it is a reference-count leak, not a remote takeover issue. Business urgency is unclear because no CVSS score, CWE, or exploit evidence is provided.

Executive priority

Handle through normal kernel maintenance unless asset context shows exposed or critical audio-platform devices. There is insufficient public evidence for emergency response, but affected kernel fleets should still be patched through standard cycles.

Technical view

The flaw is in ASoc audio-graph-card2, in __graph_get_type(). A node returned by of_get_parent() increments a reference count, but the code failed to call of_node_put() before replacement and return paths. The fix releases those references correctly.

Likely exposure

Exposure is most plausible on Linux kernels using the affected ASoc audio-graph-card2 code path, especially device-tree based audio platforms. The bundle lists Linux 5.16 through fixed stable points around 5.18.18, 5.19.2, and 6.0, but distro backports require vendor verification.

Exploitation context

The source bundle marks KEV as false and provides no evidence of active exploitation, public exploit code, or attack preconditions. Treat exploitation status as unknown beyond the stated kernel refcount leak.

Researcher notes

The record lacks CVSS, CWE, and detailed impact analysis. The only described weakness is a missing of_node_put() around of_get_parent() references. Avoid assuming privilege escalation, remote reachability, or denial of service without additional vendor evidence.

Mitigation direction

  • Check Linux vendor or distribution advisories for backported fixes.
  • Update to a kernel build containing one of the referenced stable fixes.
  • Prioritize embedded or device-tree audio systems using ASoc audio-graph-card2.
  • Track the issue in vulnerability management until vendor applicability is confirmed.

Validation and detection

  • Inventory running kernel versions and vendor patch levels.
  • Confirm whether ASoc audio-graph-card2 is present or enabled.
  • Compare kernel source or changelog against the referenced stable commits.
  • Document systems where vendor advisories mark this CVE not applicable.
