  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/cxgb4: Free debugfs on registration failure  c4iw_alloc() creates the per-device debugfs tree (dev-\u003edebugfs_root via setup_debugfs()), but it is removed only in c4iw_remove(), not in c4iw_dealloc().  When RDMA device registration fails, the registration worker's err_dealloc_ctx path calls c4iw_dealloc() directly, bypassing c4iw_remove(), so the debugfs dentries leak and outlive the freed c4iw_dev.  Move debugfs_remove_recursive() into c4iw_dealloc() so every path that frees ctx-\u003edev also removes its debugfs tree.",
