Description
A flaw was found in the Linux kernel's Platform Security Processor (PSP) network driver. This vulnerability occurs when creating a device association, where the system fails to properly check if the device has been unregistered. A race condition exists where the device can be unregistered before a lock is acquired, leading to an invalid state. This could potentially result in system instability or a denial of service.
