CVE-2023-54175: i2c: xiic: xiic_xfer(): Fix runtime PM leak on error path

In the Linux kernel, the following vulnerability has been resolved: i2c: xiic: xiic_xfer(): Fix runtime PM leak on error path The xiic_xfer() function gets a runtime PM reference when the function is entered. This reference is released when the function is exited. There is currently one error path where the function exits directly, which leads to a leak of the runtime PM reference. Make sure that this error path also releases the runtime PM reference.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel flaw in the xiic I2C driver where one error path fails to release a runtime power-management reference. The public record does not provide CVSS, CWE, or concrete business impact. Treat it as an operational reliability issue unless vendor guidance says otherwise.

Executive priority

Handle through normal kernel maintenance unless affected embedded or hardware-control systems depend on xiic. Escalate only if vendor advisories identify service impact or broader exploitability.

Technical view

xiic_xfer() obtains a runtime PM reference on entry and normally releases it on exit. One direct-return error path leaked that reference. The fix changes the error path so the reference is released consistently. The issue is tied to affected Linux kernel versions and referenced stable commits.

Likely exposure

Exposure is most likely on Linux systems running affected kernel builds where the xiic I2C driver is built in or loaded and the relevant hardware path is used.

Exploitation context

The source bundle does not show active exploitation, public exploit details, KEV listing, CVSS scoring, or a remote attack path. Exploitability and impact remain insufficiently evidenced.

Researcher notes

Evidence is limited to the CVE record and Linux stable commit references. The record describes a runtime PM reference leak on an error path, but does not include CVSS, CWE, exploit status, or detailed impact analysis.

Mitigation direction

  • Apply a maintained kernel update or backport containing the referenced xiic_xfer runtime PM fix.
  • Track Linux distribution or device-vendor guidance for packaged kernel availability.
  • Prioritize systems where the xiic driver is enabled and operationally relevant.
  • Reboot or otherwise activate the updated kernel per vendor instructions.

Validation and detection

  • Inventory running kernel versions against the affected versions and stable fix references.
  • Check whether the xiic I2C driver is built, loaded, or required on target systems.
  • Confirm vendor kernels include the referenced stable commits or equivalent backports.
  • Monitor affected systems for power-management or I2C reliability symptoms until patched.
