CVE-2022-50641: HSI: omap_ssi: Fix refcount leak in ssi_probe

In the Linux kernel, the following vulnerability has been resolved: HSI: omap_ssi: Fix refcount leak in ssi_probe When returning or breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node to possibly release the node.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel bug in the OMAP SSI driver. A reference count may not be released during driver probing, creating a resource leak. The public record does not provide CVSS, confirmed impact, or evidence of active exploitation.

Executive priority

Treat as routine kernel maintenance unless your environment uses OMAP SSI-related Linux systems. There is no sourced active exploitation signal, but unpatched kernel resource leaks can affect reliability.

Technical view

CVE-2022-50641 fixes a refcount leak in HSI omap_ssi ssi_probe. When exiting early from for_each_available_child_of_node(), the child node requires of_node_put(). Stable kernel commits are referenced, but severity and exploitability are not scored in the provided sources.

Likely exposure

Exposure is most relevant to Linux systems using the omap_ssi driver or affected kernel code paths. The bundle lists Linux kernel versions and stable commits, but distro-specific affected status requires vendor confirmation.

Exploitation context

No KEV listing is present, and the provided sources do not claim active exploitation. The described condition is a probe-time reference leak, suggesting local hardware or device-tree-related context rather than a clearly remote attack path.

Researcher notes

The record is sparse: no CVSS, CWE, or explicit impact statement. Analysis should focus on the referenced stable commits and vendor backports. Avoid assuming broad exploitability without driver reachability and platform context.

Mitigation direction

  • Review vendor kernel advisories for CVE-2022-50641 applicability.
  • Apply a vendor-supported kernel update containing the referenced stable fix.
  • Prioritize systems using OMAP SSI or related HSI driver functionality.
  • If unsure, ask the OS vendor to confirm backport status.

Validation and detection

  • Inventory Linux kernel versions across affected assets.
  • Check whether omap_ssi driver code is present or enabled.
  • Confirm whether vendor kernel packages include the referenced stable commit.
  • Document systems where vendor impact status remains unknown.
