CVE-2025-68289 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_eem: Fix memory leak in eem_unwrap The existing code did not handle the failure case of usb_ep_queue in the command path, potentially leading to memory leaks. Improve error handling to free all allocated resources on usb_ep_queue failure.
