State: Published
Severity: Not scored

Description

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.
