CVE-2025-68289

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: gadget: f_eem: Fix memory leak in eem_unwrap<br /> <br /> The existing code did not handle the failure case of usb_ep_queue in the<br /> command path, potentially leading to memory leaks.<br /> <br /> Improve error handling to free all allocated resources on usb_ep_queue<br /> failure. This patch continues to use goto logic for error handling, as the<br /> existing error handling is complex and not easily adaptable to auto-cleanup<br /> helpers.<br /> <br /> kmemleak results:<br /> unreferenced object 0xffffff895a512300 (size 240):<br /> backtrace:<br /> slab_post_alloc_hook+0xbc/0x3a4<br /> kmem_cache_alloc+0x1b4/0x358<br /> skb_clone+0x90/0xd8<br /> eem_unwrap+0x1cc/0x36c<br /> unreferenced object 0xffffff8a157f4000 (size 256):<br /> backtrace:<br /> slab_post_alloc_hook+0xbc/0x3a4<br /> __kmem_cache_alloc_node+0x1b4/0x2dc<br /> kmalloc_trace+0x48/0x140<br /> dwc3_gadget_ep_alloc_request+0x58/0x11c<br /> usb_ep_alloc_request+0x40/0xe4<br /> eem_unwrap+0x204/0x36c<br /> unreferenced object 0xffffff8aadbaac00 (size 128):<br /> backtrace:<br /> slab_post_alloc_hook+0xbc/0x3a4<br /> __kmem_cache_alloc_node+0x1b4/0x2dc<br /> __kmalloc+0x64/0x1a8<br /> eem_unwrap+0x218/0x36c<br /> unreferenced object 0xffffff89ccef3500 (size 64):<br /> backtrace:<br /> slab_post_alloc_hook+0xbc/0x3a4<br /> __kmem_cache_alloc_node+0x1b4/0x2dc<br /> kmalloc_trace+0x48/0x140<br /> eem_unwrap+0x238/0x36c
