A flaw was found in the Linux kernel. Specifically, within the USB subsystem (usbio), a memory leak occurs when a Universal Serial Bus (USB) Request Block (URB) submission fails during the device probing process. This failure to free the allocated URB memory can lead to a gradual depletion of system resources, potentially impacting system stability and performance.
