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. kmemleak results: unreferenced object 0xffffff895a512300 (size 240): backtrace: slab_post_alloc_hook+0xbc/0x3a4 kmem_cache_alloc+0x1b4/0x358 skb_clone+0x90/0xd8 eem_unwrap+0x1cc/0x36c unreferenced object 0xffffff8a157f4000 (size 256): backtrace: slab_post_alloc_hook+0xbc/0x3a4 __kmem_cache_alloc_node+0x1b4/0x2dc kmalloc_trace+0x48/0x140 dwc3_gadget_ep_alloc_request+0x58/0x11c usb_ep_alloc_request+0x40/0xe4 eem_unwrap+0x204/0x36c unreferenced object 0xffffff8aadbaac00 (size 128): backtrace: slab_post_alloc_hook+0xbc/0x3a4 __kmem_cache_alloc_node+0x1b4/0x2dc __kmalloc+0x64/0x1a8 eem_unwrap+0x218/0x36c unreferenced object 0xffffff89ccef3500 (size 64): backtrace: slab_post_alloc_hook+0xbc/0x3a4 __kmem_cache_alloc_node+0x1b4/0x2dc kmalloc_trace+0x48/0x140 eem_unwrap+0x238/0x36c
