Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. This patch continues to use goto logic for error handling, as the existing error
 handling is complex and not easily adaptable to auto-cleanup helpers. kmemleak results: unreferenced
