This patch continues to use goto logic for error handling, as the\nexisting error handling is complex and not easily adaptable to auto-cleanup\nhelpers.\n\nkmemleak results:\n  unreferenced object 0xffffff895a512300 (size 240):\n    backtrace:\n      slab_post_alloc_hook+0xbc/0x3a4\n      kmem_cache_alloc+0x1b4/0x358\n      skb_clone+0x90/0xd8\n      eem_unwrap+0x1cc/0x36c\n  unreferenced object 0xffffff8a157f4000 (size 256):\n    backtrace:\n      slab_post_alloc_hook+0xbc/0x3a4\n      __kmem_cache_alloc_node+0x1b4/0x2dc\n      kmalloc_trace+0x48/0x140\n      dwc3_gadget_ep_alloc_request+0x58/0x11c\n      usb_ep_alloc_request+0x40/0xe4\n      eem_unwrap+0x204/0x36c\n  unreferenced object 0xffffff8aadbaac00 (size 128):\n    backtrace:\n      slab_post_alloc_hook+0xbc/0x3a4\n      __kmem_cache_alloc_node+0x1b4/0x2dc\n      __kmalloc+0x64/0x1a8\n      eem_unwrap+0x218/0x36c\n  unreferenced object 0xffffff89ccef3500 (size 64):\n    backtrace:\n      slab_post_alloc_hook+0xbc/0x3a4\n      __kmem_cache_alloc_node+0x1b4/0x2dc\n      kmalloc_trace+0x48/0x140\n      eem_unwrap+0x238/0x36c","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0ac07e476944a5e4c2b8b087dd167dec248c1bdf","https://git.kernel.org/stable/c/0dea2e0069a7e9aa034696f8065945b7be6dd6b7","https://git.kernel.org/stable/c/41434488ca714ab15cb2a4d0378418d1be8052d2","https://git.kernel.org/stable/c/5a1628283cd9dccf1e44acfb74e77504f4dc7472","https://git.kernel.org/stable/c/a9985a88b2fc29fbe1657fe8518908e261d6889c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68289","score":0.00205,"percentile":0.10369,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
