CVE-2025-68312

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel’s usbnet functionality that can lead to a “free active object (kevent)” error. This issue arises during usbnet device probing and unregistration, specifically when a kevent is scheduled in a global workqueue but not yet executed before the device is unregistered, resulting in a crash when free netdev() is called. The problem is exacerbated when the device is not up, preventing the execution of ndo stop() to cancel the kevent. The resolution involves canceling the kevent before executing free netdev().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
