CVE-2023-53196: usb: dwc3: qcom: Fix potential memory leak

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: qcom: Fix potential memory leak Function dwc3_qcom_probe() allocates memory for resource structure which is pointed by parent_res pointer. This memory is not freed. This leads to memory leak. Use stack memory to prevent memory leak. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue is a memory leak in the Qualcomm DWC3 USB controller driver path. The source says allocated memory is not freed during probe handling. No CVSS score, CWE, or active exploitation evidence is provided, so business urgency should be driven by whether affected Qualcomm-based Linux systems are in use.

Executive priority

Treat as a targeted maintenance issue, not an emergency, unless affected Qualcomm-based Linux devices are critical, exposed to frequent hardware events, or resource constrained. Patch through normal kernel update channels once vendor-fixed builds are available.

Technical view

dwc3_qcom_probe() allocates memory for a resource structure referenced by parent_res and does not free it. The kernel fix changes this to use stack memory, avoiding the leak. The affected area is the Linux USB DWC3 Qualcomm driver path; exact exploitability is not described in the sources.

Likely exposure

Exposure is likely limited to Linux systems running affected kernel versions or commits with the Qualcomm DWC3 USB controller driver in use. The bundle lists Linux versions including 5.3, 5.4.251, 5.10.188, 5.15.121, 6.1.39, 6.4.4, and 6.5 as affected.

Exploitation context

The bundle does not report active exploitation, public exploit code, or KEV listing. The described impact is a kernel memory leak, which may matter most for long-running or resource-constrained devices if the affected probe path is reachable.

Researcher notes

Evidence is limited to the CVE description and Linux stable commit references. The source identifies the bug class and fix approach, but does not provide CVSS scoring, a CWE, attack prerequisites, trigger frequency, or a demonstrated security impact beyond memory leakage.

Mitigation direction

  • Check Linux distribution or device vendor guidance for fixed kernel packages.
  • Update affected kernels to builds containing the referenced stable fixes.
  • Prioritize Qualcomm-based Linux devices using the DWC3 USB controller driver.
  • Track memory pressure on affected systems until remediation is complete.

Validation and detection

  • Inventory Linux kernel versions across Qualcomm-based systems.
  • Confirm whether the DWC3 Qualcomm USB driver is built or loaded.
  • Compare deployed kernels against vendor-fixed releases or referenced stable commits.
  • Review system logs and monitoring for unexplained kernel memory pressure.
