If smb2_parse_contexts() rejects malformed\ncontext data, SMB2_open() returns without closing the handle, leaving the\nserver-side handle open and num_remote_opens elevated.\n\nClose the handle after a post-CREATE context parsing failure so the error\npath releases the remote resource and balances the open count.",
