In the Linux kernel, the following vulnerability has been resolved: USB: ulpi: fix memory leak on registration failure The allocated device name is… (CVE-2026-64332)
A memory leak vulnerability in the Linux kernel's USB ULPI driver was fixed. The issue involved the allocated device name not being freed when early ULPI device registration failed. The fix involved initializing the device structure earlier and releasing the initial reference if registration fails.
AI Analysis
Technical Summary
CVE-2026-64332 addresses a memory leak in the Linux kernel's USB ULPI driver. Specifically, when early ULPI device registration fails, the allocated device name was not freed, causing a memory leak. The resolution involved changing the initialization sequence of the device structure and ensuring that the initial reference is released upon registration failure.
Potential Impact
The vulnerability causes a memory leak in the kernel during ULPI device registration failures. While this does not directly lead to code execution or privilege escalation, it could potentially degrade system stability or availability over time if triggered repeatedly.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Since no specific patch links or affected versions are provided, users should apply the latest kernel updates from their Linux distribution vendors to ensure this issue is resolved. Patch status is not yet confirmed in this data; check vendor advisories for current remediation guidance.
