CVE-2022-50633: usb: dwc3: qcom: Fix memory leak in dwc3_qcom_interconnect_init

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: qcom: Fix memory leak in dwc3_qcom_interconnect_init of_icc_get() alloc resources for path handle, we should release it when not need anymore. Like the release in dwc3_qcom_interconnect_exit() function. Add icc_put() in error handling to fix this.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50633 is a Linux kernel memory leak fix in the Qualcomm DWC3 USB driver initialization path. The public record does not provide CVSS, exploitation evidence, or a broad business impact statement. Treat it as a maintenance/security update issue, especially for products or fleets using Qualcomm-based Linux kernels.

Executive priority

Low immediate urgency unless the organization operates Qualcomm-based Linux devices where USB stability is business-critical. Include this in normal kernel update cycles and embedded-device maintenance planning. Escalate only if a vendor advisory identifies higher impact for your specific platform.

Technical view

The issue is in dwc3_qcom_interconnect_init. of_icc_get() allocates an interconnect path handle, but an error path failed to release it. The fix adds icc_put() during error handling, matching cleanup behavior in dwc3_qcom_interconnect_exit. This is a resource leak, not described as code execution or privilege escalation in the provided sources.

Likely exposure

Exposure appears limited to Linux systems using the Qualcomm DWC3 USB controller driver. The CVE record lists Linux kernel version markers including 5.10, 5.10.163, 5.15.87, 6.0.17, 6.1.2, and 6.2, but the exact affected ranges should be confirmed against vendor kernel advisories.

Exploitation context

The source bundle shows no CISA KEV listing and no cited evidence of active exploitation. The described flaw is a memory leak during driver initialization error handling, suggesting availability or stability relevance under specific hardware and failure conditions rather than straightforward remote compromise.

Researcher notes

The public CVE data is sparse: no CVSS, CWE, exploit status, or detailed affected range is provided. Analysis should center on the referenced kernel commits and downstream vendor backports. Avoid assuming exploitability beyond the documented resource leak in the Qualcomm DWC3 interconnect initialization error path.

Mitigation direction

  • Review Linux distribution or device vendor guidance for CVE-2022-50633.
  • Update to a kernel build containing the referenced stable fixes.
  • Prioritize Qualcomm-based devices using the DWC3 USB driver.
  • Track embedded or Android-derived kernels separately from server distributions.

Validation and detection

  • Inventory Linux kernel versions across affected assets.
  • Identify systems using Qualcomm DWC3 USB controller support.
  • Compare deployed kernel source or changelog against referenced stable commits.
  • Confirm remediation through vendor package metadata or kernel release notes.
